I don't remember too much of this manga since I read it a few months ago. I do remember that i disliked the short black haired guy since I thought he was stupid af. He was the reason why the master left even though he knew of the master's feelings. So, he got some guy who worked at the place and made it look like they were doing something Inappropriate.
And he knew that the master would come through those doors. Which he did.
