TAKAMI KEIGO (HAWKS)

Hawks first notices you when he's out patrolling the streets. The sky is as sunny as your smile and he simply returns a grin, checking you out a little while doing so.It's not until the next day that he really notices you, though. It's storming so hard that he's having trouble flying- but only in an isolated part of the city. Everywhere else is calm, so it must be someone's quirk, he thinks.When he flies into the heart of the storm, he expects to see a villain. Instead, he finds you, sobbing into your hands and curled up on the dirty cement.You cheer up immediately when you see him, a famous pro hero, and the storm clears almost immediately. Sun peaks through the dark clouds until they cease to exist, all because of him.He's honestly flattered. More than flattered, really. It's almost addictive, the knowledge that he's the one that calmed your storm.You tell him about the villains that held you at gunpoint and stole your purse and he's so seething mad that he's surprised a storm hasn't appeared over his head.He's rougher than he needs to be when he catches the villains. They're in rougher shape than usual when he hands them off to his sidekicks.He goes back to check on you, see the look on your face when he hands you back your purse and tells you that those villains won't be bothering you again. You're smiling so brightly that it makes his knees weak.You don't leave your house often, but when you do, he's your eye in the sky. He even blows off some of his scheduled patrols to watch over you.Every time that something is off with you- be it a lightning storm or just a slight sprinkle of rain, he feels a need to know just what it is that upset you, and to somehow fix it and bring the sun back into your life.He wants to be your sunshine, the constant factor to keep that beautiful smile on your face and the clouds far away.He begins to feel jealous that others make you happy. Angry that you have friends. Furious when someone flirts with you.He'll keep trying to make you happy and do his best to drive others off without upsetting you.After all, he'll always know how you're feeling just by looking at you.

TODOROKI SHOTO

When Shoto first met you, he thought you had a fire quirk. After all, you were quite literally burning with righteous fury.It took a long time of observation for Shoto to realize that you weren't some secret long-lost Todoroki child and that your quirk was something else entirely.He watched as you cried literal rivers when you were sad, turned fire engine red across your entire body when you were embarrassed (even your clothes turned red!), and, yes, created tall flames whenever you were angry.Somehow, he felt like he could relate with you a little, when you had a quirk related to fire, but there was one thing he couldn't match. You were so expressive.Not just quirk-wise, no. Your facial expressions and body language always matched whatever your quirk was doing, and Shoto almost wished he could do the same.But he was awkward, had trouble expressing his emotions. The only emotion he expressed well was anger, and that's the emotion that gave you fire.A connection, perhaps?Fate?Shoto longs to grow closer to you, but he settles for watching you every time he's home. After all, you are his neighbor.He likes to see your fury fire a little too much. Maybe that's why he's always instigating issues with you.Sneaking into your house and stealing things he knows you'll need just to see frustrated flames spread up your back while you tear your home apart looking for it.Throwing things into your yard to watch your hair light up as you angrily snatched the trash off the grass, muttering about "stupid litterers".It's not right for him to enjoy seeing you with a negative emotion so much, but he can't help it. A sick part of him feels like he can relate most this way.And Shoto just can't stop himself.

BAKUGOU KATSUKI

You were always a sight to behold when you were feeling any way other than neutral.Bakugou liked all of your emotions, if he were to be honest to himself for once. He would never admit that aloud, of course.You glow brighter than the sun when happy, nearly blinding him with your otherworldly beauty.You burst into flames when you're angry, the flames always lighting up your features in the most flattering of ways.And when you were sad? You cried fountains of water while you drooped like a wilting flower, shrinking a little and looking frailer than ever before.Would you believe that sadness was Bakugou's favorite of your emotions?Sure, you were beautiful when happy and got him pumped up when angry, but when you were sad?He just wants to scoop you up in his muscular arms and feel your now-tiny form in his own.He wants to wipe your tears away until they trickled off and no longer spouted wildly from the corners of your eyes.He wanted to cheer you up a little, to watch you turn from a wilted little flower into a lightly-glowing, sheepishly-giggling mess.He likes your sadness so much that he finds himself saying terrible things to you, just to watch that transformation.He feels guilty after saying and doing awful things, to be the cause for your sadness.But to see you shivering and sobbing below him?Worth it every time.
