Shiro is very heart eyes about soft Keith (and disco ball Keith tbh). He won't drink a lot but he will nurse a big umbrella drink and try to beat Keith at a racing game. He's not very good at driving games so he will absolutely lose. Oh and I forgot but he brought his telescope up and spent some time stargazing with anyone dorky enough to join him.
Noct is on game set up and and will be pretty competitive on some games and super lazy/flirting with his boyfriends on others. Lots of leaning on them and climbing into Gladio's lap. It's his favorite gaming chair.
