Well, if you really think about it, it would be weirder if only one person knew this side of him. I don't think he really has like, FRIEND friends in this office, but it wouldn't exactly be out of place for this to happen...
@DominoSubmarine There seems to be a trend recently of titles like this one that lead with all the tropes but don't deliver a payoff because they're not actually shounen ai; I'm a little unhappy about it since it feels like I've been baited, though I still enjoy the tropes. I wonder sometimes if this is done deliberately so that the series will be more mainstream.
