So during that theorized day in between, Daiki made sadface at Yusuke sometime while Tsukasa was off making sure Natsumikan was A-OK/getting MANLY MENTORING from Kotaro.

Or Yusuke secretly forgave him somehow--but that would probably still involve Daiki doing something that would change his mind.

He probably gave him the biggest puppy eyes he could ever muster up--or perhaps stole tiny little sparkly things and left them on Yusuke's window sill as a way of saying "I'M KIND OF SORRY."
