You and Todoroki where doing a mission together, you're still in 1-A but got a mission assigned like everyone else, there were 'love' villains on the lose who'd hurt everyone that wasn't in love or acting in love with the person they were with. You and Todoroki got targetted and you pulled Todoroki with you in a small room, it was impossible to fit three people in there as two people was already hard. You both hid from the villains (State your OC and their hero costume)
