Todomomo

She kisses his cheek a lot and then he turns his head so she kisses his lips.

Kirimina

Mina roller skates up to him and tackles him to the ground so she can kiss him because he gets tall when they get older.

He starts flying with her in his arms. She probably hates it but it's romantic to him. Idk.

Kamijirou

Making a song together that's about how much they love one another

Dabi x Toga

He gives her big hugs

Nejitama

She dances with him around the house. Like she goes crazy and he's scared help him.

Mt.Kamui

Ryushot

Omg he stands behind her while she cuts up food and just holds her hand to make sure she doesn't hurt herself, but while He's there, he gives her a few kisses on the cheek.

HitoRei

She invites him into the 1-B dorms to watch a movie and because she's short they share a blanket and sometimes they fall asleep on each other or she falls asleep on his lap.

Sparring but it's romantic-

My favorite is HitoRei. The end.
