So why was he showing off his chest?
Because unlike you, he has abs.
Wow. give him some earrings and he'd look like a borderline homo vampire.
as for OPs question. I don't know the context but given his expression he seems upset so maybe he's trying to display a sense of superiority towards the opposing party?
The beauty of androgyny.
Because anime combining two different scenes.
Why on earth is showing your chest "display a sense of superiority"?
Look at this beta faggot out of touch with his animal instincts. Bet he doesn't even understand that exposing your neck is a sign of acceptance/submission.
Thank you, S&M master.
Intimidation. shows that you're physically fit and could "go".

also manly points.
He wants to know whether you want to volleyball or yaranaika
Why don't you?
