"After, then." He can't imagine someone^* of Vena's size won't be feeling some aches and pains after a night like he's described. It's not really Levi's place to offer advice, so he'll understand if Vena brushes it off. He's just hired help for the party, after all.

"I mean, it's up to you, of course." Vena's grown and very clearly in charge of his own life. Maybe Levi's just a little bit of a mother hen.

^*a regular human person.
