Mu qing starts avoiding him. Feng xin wants to feed his ego and think that it's because Mu qing is too much of a pussy to face and fight him. But no. That'll be the last thing Mu qing will ever be. Mu qing does not cower. Not even when threatened by the former emperor himself. So he knows that that's not the case. Even if Mu qing himself tells him that (which ofcourse he wouldn't) he won't believe it. So, even if Feng xin doesn't want to, he can't help but think. Why the fuck is Mu qing avoiding him? And when the truth came out, fluff ensues.

Don't deny it you know its true. The feelings you feel for him are not an allusion they're real. But not wanting to hurt those you 'love' might just end up being your downfall.
