The teams are just 1 big family. Prove me wrong. Oh that's right, ya can't. Anyway ship suggestions:

-Kagehina
-Tsukkiyama
-Kugushiba
-Kogagoshi
-Sakuatsu
-Daisuga

One day they tell the team that they are dating. As soon as the one of them leave (Whoever you think they would be protective over) The team gives them the shovel talk (Aka, hurt them and no one will find your body)
