Bakugo didn't think of you as anyone unique. You were just like any other extra in his class - happy 24/7, always smiling and laughing, brightening up the room with their presence, trying to be positive in every situation, and just a ray of sunshine - much like pink cheeks and deku. So you didn't stand out much, apart from the fact that you rarely showed any other emotion other than joy. Bakugo was an observant man after all, even if it was against his will, he noticed little things about people. So he noticed how you've never shed a tear infront of anyone, how you've never gotten mad at anyone, how you've just smiled even when people say rude shit.

And he also noticed how you always covered your arms, or specifically your veins. You always had bandages on you wherever your veins were located - as if hiding something even though you brushed it off as just a scratch. Only you knew the truth about how you took drugs to be this happy, basically what you would call a happy drug.

Sure, you two weren't close and all, but he wasn't a complete asshole. So when he saw you excuse yourself to your room in the middle of the class 2-A dinner, he followed you. He sneaked behind you, until you disappeared into your room. And fortunately, you left the door creaked open a little bit since obviously, you wouldn't expect anyone to follow you. He peeked from the door. And then he saw it. The small syringe full of something in your hand as you took of your bandage - revealing multiple poked areas in your veins.

At first, Bakugo didn't process what it was. He thought you were self harming by cutting yourself, but this was completely different..? What were you...oh. Drugs. You were drugging yourself. For what exactly? He didn't know, but he couldn't just watch. Bakugo burst inside immediately. "What the fuck are you doing?!"
