The Kageyamas start having movie nights as a bonding activity except Mob keeps wanting to watch action and cheesy romance movies and it kills Ritsu who only watches character study dramas and pretentious abstract bs

But then Mob calls Teru over to watch stuff with them and is joyous to find he also enjoys B movies and mindless fun so Ritsu has to sulk in the corner of the couch because he only understands the entertainment of needless violence when he's the one performing it

BUT he gets to pick a movie eventually and puts on some obscure film that's older than all of their ages combined and Mob falls asleep 15 mins in but Teru is like, really into it

They watch all of it in utter silence before spending the next few hours discussing themes and theories and interpretations and they disagree a good chunk of the time and argue about it in the most passive aggressive faux polite way possible but love every second of it that's Enrichment for them (Mob is still sleeping)

So movie nights turn into fights over which Kageyama gets to watch movies with Teru that day which isn't good for bonding with each other but it surely is for bonding with Teru
