summary: your child comes home from school one day begging for a playdate with their new friend - whose dad happens to be an intimidating and reserved hero. You approach him expecting the worst, but he’s more interested in you and your past than you realize. What could come of this unexpected encounter?
Rei looked over at Mei, her feet swinging wildly underneath her desk. The last lesson of the day was moving too slowly, especially since the girls were excited for their first playdate at Rei’s house. Sighing, Rei put her head on the table, hoping that not looking at the clock would make time move faster. All she wanted was to run home to play dinosaurs with Mei-
“Alright everyone,” Teacher Park said, “It’s time for us to pack our bags and line up!”
Rei nearly shot out of her chair, shoving everything in her bag and eagerly waiting for her name to be called for the line.
“Don’t forget to practice adding and subtracting,” Teacher Park shouted over the sound of students packing their things, walking to stand next to the door and beginning to call names.
“Mei L/N!” he said, nodding as she ran up to him, “You’re going home with Rei today, right?”
“Awesome! Go stand next to the door for me, please!” he said, holding his hand out for the daily goodbye high-five, which Mei gladly gave.
“Rei Kim,” he said, a bit startled by the speed at which Rei ran up to him, “You two can stand next to each other in line today!”
Holding out his hand yet again, Rei reared back to give a big high-five. Upon impact, however, Teacher Park’s arm jolted back suddenly, startling Rei a bit.
“Sorry,” he said with a grin, shaking out his arm, “You must be excited to go home today! That high-five had a bit of a shock to it.”
Surprised at that, Rei looked down to see little electric sparks moving around her fingers. She smiled apologetically, shaking her hands to try and get rid of the electricity on her hands.
“Sorry, Teacher. I didn’t mean it!”
“I know you didn’t, and that’s okay! Now, let’s finish calling the line so you can go home.”
He resumed calling the list of names, and Rei went to stand behind Mei, still wiggling her hands furiously. Mei turned to look at her actions, fascinated by the way her powers looked.
“Hey Rei,” she whispered, tearing her friend’s attention away from her hands, “Is your daddy coming to get us?”
Rei nodded her head at lightning speed, “Yeah! I can’t wait to show you my house!”
“Me too,” Mei whispered, pointing to her backpack, “Baba doesn’t know, but I brought my dinosaur toy with me!”
Gasping, Rei looked at the backpack, noticing that it was indeed much bigger than usual, her excitement rising again.
“H-hey Rei,” Mei giggled, pointing to Rei’s hair, “I think you’re making everyone’s hair stand up.”
Looking around the room, Rei also began to giggle as she saw that Mei was right, laughing even harder when Mei’s hair started to stand up and she tried to keep it down.
“Okay, everyone,” Teacher Park said, clapping his hands to get the class’ attention, “Follow me!”
Opening the door and walking out, the teacher led the line of students down the hallway, the class all laughing together as they all poked each other, finding the shocks of residual static electricity hilarious. When they finally got to the exit, Rei made sure not to touch the metal door, remembering that it could be dangerous with her power, and instead ran outside right behind Mei, immediately scanning the scene for her-
“DADDY!” Rei shouted when she spotted Younghoon, running over to him with Mei trailing behind.
Younghoon smiled at her, noticing the yellow bolts of electricity zipping around her arms and legs as she ran at him.
“Hey there, Sparky,” he said, “Are you feeling okay right now?”
Rei’s cheeks turned red, looking down at her hands.
“Daddy, can you help me make it go away?”
“Yes I can,” he said, opening the gate wide for her and Mei to walk through.
“Mei,” Younghoon said, “Stand next to me, please. Rei has to get rid of some energy.”
Nodding, Mei did as he said, her little hands clinging onto her backpack straps as she looked from Rei to Younghoon, curious of what was about to happen. Rei had walked a bit down the sidewalk and was now carefully watching her father.
“Do you remember how to do it?” he asked, one of his hands slipping inside his jacket to grab onto something.
Nodding vigorously, Rei’s hands balled up into fists.
“It’s like a big punch!”
“That’s right. Alright, watch carefully. You too, Mei.”
Younghoon quickly removed his hand from his jacket, throwing a small piece of metal high up, which he then suspended midair with his power. The electricity around Rei charged up quickly; she stared at the little bar, quickly punching the air in the direction of the metal, a large lightning bolt erupting from her hand and striking the metal, dissipating into the sky above them. Mei watched this happen with eyes wide, completely enraptured by this display of power.
“LOOK, I DID IT,” Rei shouted, jumping around the sidewalk in joy.
“I’m proud of you, Rei,” Younghoon began, the metal finally falling from the air back into his hand, “Do you feel better now?”
“Uh huh! No more shocks!” she said, wildly punching and kicking the air now.
Mei erupted into applause, eyes shining with admiration for her friend.
“Rei,” she cheered, “That was so cool!”
“Thank you!” she replied, running back to her father and friend, “Did you see me? I was like a real hero!”
Younghoon smiled, placing the metal back into his jacket, and reaching his hands out towards the girls.
“You did amazing,” he said, “Now, both of you need to hold my hand so we can go home.”
“Okay! Mei, wasn’t that so cool?” Rei said as they took Younghoon’s hands and began to walk down the sidewalk.
“Yeah!” Mei agreed, swinging her arm as she walked, “You’re so amazing!”
“You did do great,” Younghoon said, quickly squeezing his daughter’s hand, “Now we should practice using electricity whenever you want instead of just when you get excited.”
Rei nodded, her face looking forward with determination, making Younghoon’s heart swell with pride. They walked in silence for a bit, until Younghoon felt Mei tugging gently on his arm.
“Why did Rei have to hit that metal thing?”
Younghoon thought for a moment, trying to figure out how to explain it to a child.
“When Rei gets like that, she’s overflowing with electricity,” he began, looking down to make sure the kids understood, “So she needs to get it out quickly, or else someone might get hurt if they touch her, since electricity is dangerous.”
Mei nodded knowingly, “Baba says I can’t touch electricity stuff, because it hurts.”
Younghoon felt his ears warm up at the mention of you, but he carried on.
“Y/N is right, which is why it has to get out of Rei fast. Electricity likes metal, so it’s easier for Rei to shoot her electricity at metal.”
Mei gasped, leaning forward to look at Rei.
“Rei, maybe you need my baba’s special gloves that they wear for electric stuff!”
That might actually be helpful, Younghoon thought, before a question came to mind.
“Mei,” he said, catching her attention, “What does your baba do with electricity?”
“Building things!” Mei said, smiling up at the man, “Baba builds lots of things to help with sending packages!”
“Like when they were a hero and made stuff?” Rei asked, her eyes shining in excitement.
“Yeah! They have a special room for it and everything!”
Younghoon cleared his throat, getting the attention of the children.
“We’re here,” he said, directing them towards the door, “Come on, let’s go inside and wash our hands.”
Walking inside and taking off their shoes, Mei looked up at Rei with a mischievous look in her eye.
“Baba doesn’t know,” she said, “But I found a video on the internet of them doing hero stuff.”
“Woah,” Rei gasped, pulling on Younghoon’s hand, “Daddy, can we watch the video?”
“Hold on a minute,” he said, removing their backpacks and neatly placing their shoes next to the door, “You both need to wash your hands.”
Younghoon would have been lying if he said he did not want to see the video; after hearing of your hero past, he had attempted to search for information online about you, but this proved to be impossible without knowing your hero name or agency. He had even asked Sangyeon if he knew anything, which only got him shrugs and more questions about his relationship with you.
“Hey, Mei,” Rei said, speaking up just enough to be heard over the sound of water running, “I think my daddy likes your baba.”
Mei stared at Rei with wide eyes, “Really?”
“Yeah,” Rei whispered, “My daddy never wants to know anything about anyone, but he asks a lot of questions about your baba.”
Mei gasped, “My baba asks a lot of questions about your daddy too! Maybe they like him!”
“What’s going on in here,” Younghoon said, finding it suspicious the way the girls suddenly stopped talking, “You two have been washing hands for a long time.”
“We’re talking about Y/N,” Rei said, turning the water off, “Can we watch the video now, please?”
Looking down at the girls’ pleading faces, Younghoon felt his resolve wear down.
“Fine,” he sighed, “Dry your hands, I’ll go turn my computer on.”
“YAY!” Rei cheered, “Daddy, can you give me the towel ple-”
“Wait! I wanna do it!” Mei said, her hands scrunched up in determination, “I wanna show my powers too!”
Younghoon raised an eyebrow, unsure of what she meant by that, but he thought it would be best to not object.
Mei clapped her hands together, surprising Younghoon when the hand towel suddenly appeared in her hands.
“Just like baba taught me!” Mei beamed, handing the towel to Rei, who was clutching her friend’s sleeve and jumping around. Younghoon looked at Mei in wonder, realizing that she had inherited your power, and even more curious to see the video of your heroics.
“Well, come on,” he said, walking towards the living room, “Let’s watch this video.”
“OKAY,” the girls cheered, following behind Younghoon, sitting down on the couch on either side of him as he powered up his laptop.
“Mr. Younghoon,” Mei said, poking his arm, “I can type it in! I remember how to spell the name!”
“Alright, go ahead,” he replied, patiently waiting for her to type the name.
Mei tapped the screen, “It’s this video!”
Nodding, Younghoon clicked it, reading the title while the video loaded.
“Hero transports runaway train,” he muttered, “Not giving any good details with a name like that.”
Despite that complaint, Younghoon went silent as the video began, trying to keep his eyes open as long as possible to take in all of the details. The video showed a train speeding towards a train station, where another train was sitting and picking up passengers.
“Oh my god!” the person filming screamed, the fear in their voice tangible. Suddenly, a figure leaped down onto a rooftop, before appearing on top of the speeding train.
“That’s baba,” Mei whispered, making Rei and Younghoon lean closer to the screen. You moved your hands in a circle, making a glowing orange ring appear in the same pattern. Younghoon felt his breath hitch as the train came closer to the station, but you thrusted your hands forward, the orange ring launching forward and growing larger.
“What is that-” the person filming said, stopping their sentence to inhale sharply as the train approached the glowing circle; Younghoon felt his heart beating as the train entered the ring, realizing that the train was disappearing through the portal. The person filming also seemed to notice, suddenly moving the camera to the tracks on the other side of the train station, gasping when the runaway train was coming out of a portal on the other side.
Younghoon’s jaw dropped in shock, watching as you held the portal open until the entire train passed through, jumping onto the track and clapping your hands together to make the portal disappear.
“And now, baba disappears,” Mei said happily, as you suddenly teleported somewhere and the video ended, “They’re so cool, right?”
Rei nodded, “That was a huge train! Your baba is a super cool hero!”
Younghoon slumped on the couch, in shock at what he had seen. He knew teleportation type powers were exhausting and for the users and extremely difficult to use with precision, but your control over it was nothing short of amazing.
“That was incredible,” Younghoon said quietly, still staring at the computer screen.
Mei jumped to stand on the couch, striking a pose like cartoon heroes did.
“Some day, baba is gonna teach me how to do that! And I’m gonna be a cool hero too!”
“Me too!” Rei exclaimed, also standing on the couch, “I’ll be a cool hero like daddy!”
“We can be a hero team,” Mei gasped, her eyes sparkling while she imagined being a hero.
Rei jumped over Younghoon’s legs, grabbing Mei’s hand and pulling her onto the floor.
“Let’s go play dinosaur heroes!” Rei shouted, dragging Mei to her room, leaving Younghoon alone in the living room.
He was still staring at the laptop, his hand moving to replay the video every time it ended, eyes desperately searching for any details that could be used to learn about your past.
Y/N, he thought after several replays, Why can’t I find anything about you?
He paused the video right when you turned towards the camera, staring at the small image of you and sighing.
“Y/N...why do I always find myself wanting to know more about you?”
You quickly pulled herself away from your work table, nose scrunching up as you let out yet abother big sneeze that startled the cat.
“Gosh,” you said, rubbing your itchy nose, “Either someone has a lot to say about me or I’m suddenly allergic to you, Kitty.”
The cat merely flicked its tail in response, and you sighed, hunching over your table again as you worked to send a package out. Once it was sent, you sat down on a chair, taking slow breaths to regain some energy, thankful that the work day was almost over.
“Sometimes I wish I had all of my power, it would make work way less tiring,” you groaned, talking to no one - except Kitty, that is.
“But then again, if I was at full power, I might still be doing hero stuff.”
You sighed as your computer dinged, signaling the last few orders of the day being placed, stretching and standing at your station.
“I didn’t hate being a hero,” you explained, quickly grabbing the items you needed, “But I’m just too worried about Mei to do something as dangerous as that.”
You quickly attached the label on a box, carefully reading the address before clapping your hands, taking a deep breath once it disappeared.
“Maybe I wouldn’t feel so worried if I had someone reliable to support me, like Younghoon-”
You went dead silent, a furious blush spreading across your face when you realized what you had just said, your eyes wide as you stared at Kitty, desperate to clarify the situation.
“N-not that I like him or anything,” you stammered, “But I just think he’s dependable and responsible! I mean he’s a single dad and has a full time job!”
You grabbed the last items, quickly packaging them while still talking to Kitty, who responded by tucking her feet under her body, resembling a loaf of bread.
“Not to mention that he takes really good care of Rei, he's interesting to talk to, he’s kind and considerate - even if he does come off a little cold - he’s helpful, and handsome…”
You trailed off, collapsing in your chair as realization washed over you, feeling like your heart had stopped. You slowly turned, looking at Kitty like you had a shameful secret you couldn't keep anymore.
“Kitty...I think I have a crush on Younghoon.”
