Shoto Todoroki

You were left on duty in the classroom with Shoto. Suddenly, your classmates rush in, grab you and Shoto, shove you into a sturdy cabinet, and prop the door shut with a chair for good measure. Laughing, they leave—with no plans to return.
It's cramped and dark inside. In the darkness, you try to grab your phone, but your battery is dead, so you put it back. As you put it away, your phone falls over due to the cramped space. Now you're definitely in an awkward and embarrassing situation.
