yeah, the new manager is called a "him" by the boss.
Isn't it becuase of his wide shoulders?
The scene i'm talking about is when the two MC's first meet, when the mangager is running down the hall towards the door to the room. It is before you see his shoulders so you should know even before that.
You should have known even before reading it...There's no or rarely any yaoi that would have a female as a main character. And someone who appeared at that timing has got to be a main character.
You don't say? Sarcasm aside, i think we were wanting to look at in-manga evidence that the manager was a guy before the big reveal. If the summary hadn't been given we wouldn't even know that the manager WAS one of the MCs.
All the comments about how they knew Yujin was a boy and things like that XD More like, who wouldn't notice, it's just that obvious.
