Imagine Atsumu getting too drunk at a party and decides that tonight will be the night where he confesses his undying love for Hinata Shouyou.
"Shouyou-kun!" He calls while struggling to climb the bar counter. "I've been in love with ya for the last 10 years! Please be my boyfriend! I dedicate this dance to ya!" And then proceeds to do the worm.
"Tsumu, ya idiot! This is yer and Shouyou-kun's wedding reception! Stop embarrassing yerself!" Osamu turns his head to Shouyou. "Do ya think you've made the right decision of marrying this guy, Shou-kun? It's never too late to back down."
