It started, as all great tragedies do, with a mother cleaning her son's bedroom. Mitsuki Bakugo had only intended to grab the laundry. A simple task. In and out. But the universe had other plans, and the universe was apparently feeling extremely messy that day.

Katsuki Bakugo, seventeen years old, third-year U.A. student, future Number One Hero, and certified menace to society, felt a cold chill run down his spine. And not the "I'm about to win a fight" kind of chill. The "my mom just found something she was never supposed to see" kind of chill.

His tablet.

His unlocked tablet.

His unlocked tablet with the screen facing directly toward him, displaying a folder that made his entire soul leave his body for approximately three seconds.

On the screen was a folder labeled "📁 Y/n ♡." Inside? 1,847 photographs. 216 videos. 43 voice recordings. And a document lovingly titled "Things She Likes (DON'T FORGET)."

And because Katsuki Bakugo was one of the pettiest human beings to ever walk the earth, a dark thought began to form in his mind. If he was going down, he was taking every single one of those lovesick idiots in Class 1-A with him. Because he knew damn well he wasn't the worst one.

Not even close.

Somewhere in the distance, a storm was brewing. And it was shaped like a very angry blond with a PowerPoint presentation and absolutely zero impulse control.
