I agree w/ this. These two scenes also seem like foreshadowing:

And probably Jian is hesitating to tell him everything because he wants to protect him. But this only gets Zhan angry because he also wants to help Jian and doesn't like not knowing what's going on.
I kind of figured he knew but didn't think Jian Yi would tell him seriously. But sad cause that forehead kiss makes me think he's gonna say I know, but I'm sorry I can't return your feelings.....I just want to stay friends.
