He overdrank

Venti was your..drink buddy who was in love with you.

And well, today, he has drunk TOO MUCH. Drank to the point he was all clingy and flirty with you..not saying he isn't always like this, but he was more than usual.

Venti put his head on your shoulder and hicced as he giggled.

"Oh, Amor, you're so pretty..~" Venti said with a smirk..even blush on his face- that's probably the alcohol in him..unless?

Venti leaned closer to you, he nuzzled your neck with his face as he smiled.

"Amor, I..love you." Venti has hicced out as he put his hand over yours.

"Please don't leave me like he did.." Venti mumbled, there was a hint of sadness behind his tone as he clung into you.
