Seems like but let's give mo a benifit of the doubt because we all know that it's just first experience to him.. and we all know that he tian was totally sweet and how he so affectionate to mo since the beginning..
I think he's just a tsundere, like he cringes and gets embarrassedif he has to admit it so he hides it
He is the kind of people that gets mad when he gets shy, since Tian is the kind of guy that teases a lot they end up having this kind of relationship when they fight constantly but is not serious.
So all this behavior is because Mo is scared of people finding out that he likes He Tian??
