It always ends up in one of them apologizing a day later. If todoroki is apologizing he gives her flowers, if Momo is apologizing she gives him homemade cookies.

Kirimina

They literally can't fight. It's too pure.

Miruhawks

Week long grudge and a temporary breakup because Miruko holds long grudges.

Iidamei

Mei sleeps on the couch willingly and Iida gets lonely.

Kamijirou

Kaminari usually starts the fight. He usually ends up just hugging her when she screams and cries at him because that's how serious it got.

Dabi x Toga

Someone dies

Nejitama

Nejire tried to find out what she said wrong and pesters him. He doesn't talk to her even though he really wants to but he's too scared to say anything, it makes her really anxious and she thinks he hates her, so she cries and then he feels bad and then they're both crying.
