@read lots of manhwa if this is what it is, sounds like bullshit to be honest. most (drinking aged) people i know do shots, and hooking arms (aka: a love shot) while downing the drink is a pretty common mimic to make it a bit more fun. and if you think the muse thing is bad, have you never play-flirted with your friends? especially when drinking? it's weird to even think this could lead to cheating
oh no, a signature !
Spoiler!
idk what to put there anymore
