When I read your comment, I imagine that Nanjo would be mad, but not in a burstful way. He would wake up in a blanket as Mokyeon would greet him with a drink, implying that Mokyeo already planned to wake him up and explain. Nanjo would look at him with sharp eyes, then down to the corner of the bed reminiscint about last night. Nanjo would close his eyes, then ask.
I do hope that for the opening of season 2, they will have a communication period or something similar to it.Then after tying loose ends, it would be fun to know more about their past.
But that is just me.
I would absolutely love that but I feel that drama is coming our way but ultimately, I hope they end up together. I know it’s gonna get saucy - I can see Nanjo being a bit angry bcuz of what happened n he won’t accept it. I want that scene where Nanjo holds back n is figuring it out but then he goes fuck it I like u too n they have this wild sex at the end of S2. I like the build up to b extra spicy ε=ε=(ノ≧∇≦)ノ

Theories yall, theories! Do yall think Nanjo will be mad when he wakes up?? I think he will
