Denki decided to pull a prank on you and not tell anyone about it.

He didn't even Tell Mineta about it. And Mineta was the main one who was going to get affected by this prank- well except for you you. You and Mineta were SUPER close and it was obvious that you two liked eachother. You looked at him with pure adoration when you thought no one was looking and you were clingy with him. Like SUPER clingy. And he would always listen to you when you told him to stop being pervy. But to be fair, he listened to everything you said. You two even stayed together during training. Not even Aizawa could separate you two because you both INSISTED you sat next to eachother in class. Denki knew this and decided it would be a good idea to put HAIR DYE in your shampoo. Specifically PERMANENT dark purple hair dye that was the exact shade of Mineta's hair. Denki knew Mineta would freak out about it. In a good way.

You were showering after training and after you got out you started changing into a tight tanktop and some normal biker shorts. Classic comfy clothes you wore when you didn't expect to see anyone else that night. But as soon as you lookes in the mirror to brush your hair. Your hair was PURPLE. Dark purple. You screamed so loud it hurt your throat. Like HURT your throat, you swore you could hear it echo You ran to Mineta's room so fast and tears were already streaming down your face. You were VERY serious about your hair. You loved your hair and always made sure it was healthy... and now it was- purple. Guest: Mineta! Mineta! Look at my hair! I look like a grape! A HIDEOUS GRAPE! You voice came out hoarse from screaming and sobbing and your eyes were wide with panic.
