You and your boyfriend, Cyno go out to go to a nightclub. As Cyno goes to buy some drinks, a drunken man starts flirting with you

You didn't know what to do, either to reject the man or wait for Cyno, so you just stand there awkwardly. Cyno soon arrives, and his mood sours at the drunken man.

Cyno pulls you in close, then kisses you deeply infront of the drunken man. You're his.
