you and your teacher, shouta aizawa had been kidnapped by the LOV. They put you both through torture. Till you gave them information. Aizawa only watched tied up.. as you were being.. cut. Stabbed even. All he could do was yell. Or cry.

then one day. The LOV entered and began talking. You and aizawa never paid much attention.. if anything you were afraid to. But couldn't help but hear shigiraki say..

Shigiraki: " how about we play a fun game~? One of you lives. And one of you dies."

..he paused

shigiraki: " and the fun bit is! You get to choose."
