Imagine Karasuno going to the movies.
As soon as the film starts, Daichi puts his arm around Suga and Suga leans on Daichi’s chest and they stay like this until the end.
Kageyama and Hinata sit next to each other but they try to get as far from each other as possible (they are really embarassed). With time they get more and more confortable. They share popcorn, so their hands touch sometimes (accidentaly or not really) and eventually they end up holding hands.
Tsukishima awkwardly puts his arm around Yamaguchi by pretending to strech. When Yamaguchi asks about it, he just gets a “shut up” in response so he makes himself confortable in Tsukki’s embrance and focuses back on the movie. Tsukishima can’t concentrate on anything other than the fact that Yamaguchi is in his arms.
Noya kind of just suggles into Asahi, and the latter doesn’t mind. They both focus on the movie, and without realising it they do really sweet things like feeding eatch other or letting the other have a sip of the drink before having it themselves ect.
Tanaka is too much into the movie to notice all the gay around him.
