You're giving someone else attention in a study group, You and Venti are in separated group. He's watching you from the corner of his eyes while working on the project with his own group that's not really far from yours. You keep talking to the leader of your group and gives the person the attention without even glancing at him.

He glares at the person, the person feels strange, Soon you glanced at Venti and he smiles at you and winks "Hm? Oh, nothing~" then he continues on his project..
