~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

∆ So let's start with behaviors around you.

∆ Izuku can never ever work up enough courage to talk to you himself. He's totally fine just watching you from behind a tree or across the street or from your window...wait wha-

∆ If he did get the opportunity to talk to you, whether it be him walking up to you or vise versa, expect a lot of stuttering, freezing up, blushing and possibly him running away out of sheer nervousness. (Of course he kicks himself afterwards for dashing off from the love of his life.)

∆ Stalks you 100% of the time. From when you leave your house to when you walk back at the end of the day. During the night, he'll watch out from your window to make sure nothing happens to you. (And to totally not take pictures of your beautifully peaceful face while your sleeping-)

∆ This boy is definitely the type of yandere who would be so obsessed with you that if you left or died or simply rejected him, He. Will. Commit. Self. Delete.

∆ He would also guilt you into staying with him but saying he can't live without you or else he'll end his own life. And you, not wanting the guilt of someone dying because of you, stay with him. (Of course he wouldn't resort to this unless he was really desperate and had no other options.)

∆ Izuku hates it when you get hurt. Whether it's just a simple paper cut or a sprained ankle, he will panic.

∆ He just can't stand the idea of his future partner in pain and injured so every night while you're sleeping, Izuku will change your bandage if needed, prop your injured body part on top of pillows, anything you need to make you as comfortable as possible when you wake up.

∆ Also needless to say, this boy has like 20 notebooks dedicated to just you. Every little detail about you is instantly recorded in Izuku's book. From your favorite food, drink, music, place to go, movie, TV show, and style of clothing to your sleeping patterns, morning routine, route to school, class schedule, nervous habits, search history, etc.

∆ Of course, like every yandere, Izuku is not afraid to kill anyone who stands in the way of you and him. Even if the person happens to be a close friend. No one will stop him from getting the love of his life. This boy will turn from a innocent cinnamon roll to a cold, sadistic murder in a matter of seconds if someone pisses him off enough.

∆ I bet his killing techniques differ depending on how much the person is seeking your affection.

∆ Like, if a random guy was flirting with you, Izuku would give him a little stab in the back or on the side along with a little warning to stay away from you. That usually works.

∆ But someone has the audacity to flirt with you, consume your precious time by hanging out with them, and ask you out...Oh, be prepared to say goodbye to him. Izuku will not tolerate anyone trying to steal his angel away. Even if it was someone from his class, he would not care.

∆ Izuku will definitely take his time with torturing the person if they really piss him off by getting too close to you. He wanted to be the only guy in your life.

∆ The boy is actually pretty good at covering up a murder scene. Always gets away with it. No one suspects a thing. Why would they? There's nothing hiding under that sweet, nervous smile.

∆ Izuku would definitely leave little love notes and flowers in your locker and doorstep because he's too shy to say them to your face. Every time he sees you read them and smile, his heart explodes and he nearly passes out from happiness.

∆ If he was going to confess to you, he would do it near or at the place he first laid eyes on you.

∆ If you accept; Not even the sun could compete with the brightness of Izuku's giant smile when he heard the words he was so desperate to hear. At first he thought it was a dream, but you reassured him that it was real. He immediately engulfed you into a tight hug while crying. It was the happiest day of his life.

∆ After that, Izuku will follow you around like a lost puppy. (Not that he already didn't but this time you're aware of it xD). Anything you need, he will bring it in 2 seconds flat, no questions asked. He'll try to spoil you as much as possible with gifts, cuddles, kisses, praise, loving words, etc. Anything to make you fall in love with him as much as he is with you so that you wouldn't want to leave him.

∆ But of course, him being your boyfriend will make his protectiveness grow even more. Now that he finally had you, he needs to keep tabs and stay fully aware of any potential people who might steal his beloved away.

∆ This boy was already planning your wedding and fantasizing about you two's future family the day you accepted his confession.

∆ Izuku seriously worships the ground you walk on. To him, you are his savior, his angel, his god/goddess, his everything. Like I said before, if you're not in his life then he doesn't want it.

∆ He is a little clingy around you, especially with other guys present. He doesn't want to be alone ever again.

∆ Okay, now let's talk about if you reject his confession and he resorts to kidnapping you.

∆ Izuku will never purposely hurt you, even when he's kidnapping you. I'd imagine he would drug you by putting something in a drink and offering it to you. Then take you while you're unconscious. A simple and easy way to keep you for himself without any force or harm :)

∆ Unfortunately, he will have to tie you up and wrap cloth around your mouth to make sure you don't try to escape. BUT instead of rope, he'll buy the fluffy handcuffs because they're more comfortable and he doesn't want you to get rope burn.

∆ Now, Izuku isn't a complete monster. He would make you meals, hydrate you, and give you pillows to make the chair you're tied to more comfortable.

∆ Izuku would keep you locked in his room. He'd talk to you for hours as if you're not there against your will and tied up. Izuku would only take off your gag to get your answer for something. And if you're good and promise to not run away, he'll even untie you and let you walk around the apartment.

∆ You're probably wondering "Where is Inko in all of this? Wouldn't she know if her son kidnapped someone?"

∆ Well, I'll let you decide what happens to her

∆ All in all, this boy lives for you and you alone. His love and obsession for his angel is the one thing that keeps him determined to live. Izuku is completely infatuated with your existence. The boy's only goal in life is to make you his. No matter what he has to do, no one will take his angel away from him. Or else...

"Darling, I'm home~"
