He decides to leave Jean.

As tempted as it was to further indulge himself with Master Jean's body, Venti decided not to. Jean had always been a devote follower and a hard worker for Mondstadt, so Venti decided not to exploit her body anymore than he ought to. In the end he simply walked her body back to bed and left it. He had finished most of her work so it was only fair he let her rest afterwards.

That said, he was still feeling the urge to possess. While Master Jean was off limits to him, surely he could still have some fun possessing other women in Mondstadt, or perhaps other Anemo wielders. With that in mind, a sneak plan formed in his head as he disappeared into the night. He knew just who to take now.
