Even more yandere mha oneshots!

♡~Katsuki Bakugou~♡

How you two met

You two technically met during middle school, but he never acknowledged you so that doesn't count. You two only truly met once you'd both graduated high school. You had gone to a normal high school, since your Quirk wasn't all that great for Hero work, so you two haven't seen each other in a long time.

You two would officially meet when he, as a Pro Hero, would save you from a Villain. He wouldn't realize it's you at first, though.

Falling in love

Bakugou would wonder to himself why that civilian he saved seemed so familiar. "I don't think I've ever seen them before, so why do they look so damn familiar?" And then he would realize. He would realize that he went to school with you for four years, he just never cared to acknowledge you.

He would get this strange feeling. Why does he want to get to know you? What reason would he have to want that? It doesn't make sense to him. Maybe it's just that he knows now he was a horrible person back then? So does he just want to apologize? Yes, that has to be it. There's no other possible reason.

He'd deny the fact that he's falling in love again and again, until one day he just isn't able to anymore.

Kidnapping

Bakugou would go to your house in the middle of the night. He decided to not get to know you in a normal way, and chose the easier route of stalking you instead, so he knows everything about you. Everything he needs to know.

Bakugou would not be subtle with his kidnapping. He wouldn't try to get you to trust him first, he wouldn't even be quiet about it, he'd just kick the door on, and begin his hunt.

When he inevitably finds you, he'd pull you out of your bed and keep you in a choke hold. "You'd better keep your mouth shut, sweetheart. If you don't want to be blown to bits, that is~"

He'd drag you all the way to his house, using threats to keep you quiet.

Life with Bakugou

You'd be fucking terrified of him, since you don't at all remember who he is, so your life with him would be a bit... rough at first. To be honest, your life with him would be rough at first regardless of whether or not you remembered him. He's a hard person to please. Whenever you do anything, it's a 50/50 chance you piss him off. But hey, if you're into being degraded you're in luck!

Whenever you ask him who he is, he'd just tell you "You know my name, that's all you need." or "You know who I am, idiot." Whenever you ask him where you are, he'd just say that "It doesn't fucking matter!"
He's constantly threaten to kill you, keeping you chained to him by fear alone.

Your life with him would get better eventually. I'd say after a month or so, maybe two months. Once you learn what he wants you to be (and learn how to manipulate someone into calming down), your life would be at least a bit better.

He'd be at least kind of caring towards you... sometimes.

Your life with him, even once it gets slightly better, would be horrible.

Killings?

Oh yes, he would definitely kill people. He'd kill a lot of people. Your parents, siblings, friends, basically anyone who would notice that you're missing. If you talk to anyone, they'll be dead the next day.

Oh, but it's not just  that he'd kill people. He'd make you watch. And he'd make sure you know the death was your fault.

The escape

Bakugou would be one of those rare yanderes, the kind who actually lets you leave the house. He does so without fear of you running away, because he knows you're too scared of him to even attempt that. Also, he never lets you leave the house without him, just to be absolutely sure. Against better judgement, that is when you would decide to run away.

You wouldn't get far. He'd find you within five minutes, and drag your ass back home.

Great job, you just lost your leaving the house privileges.

Punishments

Bakugou would be merciless with his punishments. Yes, he loves you, but making sure you never do that again is more important. He'd do a lot of things in the realm of physical violence to make sure you know not to leave him, including burning you with his explosions. Your punishment would last a few days, as long as it takes for you to say "I'm sorry, I'll never do it again!"

He would make sure you knew what you did was wrong.

He wants you to know that, if you ever try leaving him, you'll go through this again.

Stockholm syndrome

If you were to never attempt escape, you'd develop this. He clearly loves you, who are you to deny him that love? You'd find some way to justify everything he does to you, and eventually, you'd somehow convince yourself you love him back.

If you were to try to escape, however, I don't think it'd happen. He'd definitely break you in some way, but I think it'd more so be accepting everything he does to you as just a normal part of your life rather than you falling in love with him. If you were to go this route, he'd probably just get bored of you some day and kill you. If you don't love him back, what's the point of keeping you around?

When he hears you say the words "I love you", he'll pretend he doesn't care. Inside, though, he'd secretly be very happy. You two would start a family, regardless of your opinion on children. He'd probably convince you into thinking you want them, too.

Your life would be Hell, but you can't really do anything about it, so why bother complaining...?
