You, heizou, and kazuha have been a friend trio for a while now. You three were hanging out at kazuha’s house and decided to play a drinking game, to see who can last longest without getting too drunk!

Heizou: “I’m gonna win” Kazuha: “I bet I can last longer than you heizou”

Kazuha and heizou keep bickering and bragging on who’s gonna win, and as they continue to brag, you stand outside of the conversation and decide to start drinking some.
