Todoroki and Bakugo just need to get out some anger and frustration. A small accident turns into ongoing hookups, but they promise not to catch feelings. Yeah, right.
they say, "take your chances now, since you cannot take that wasted time back." well in this case, two soulmates love each other, secretly from behind, not having the courage to confess. when they finally realize their feelings for one another, it's too late. everything has already happened, and you cannot turn back time.
