OKAY also, ZH-XAT scene in ep 27. The way ZH knows that the turmoil in his heart could only lessen a bit if he was with Antu. We see ZH cry for the first time in front of someone other than his masters and friends. Antu lets him have his peace too.
If the marqius loved anyone ever in his life, it was ZZX's mom and him. The same marquis who didn't bat an eye on hearing the death of his wife and elder son, because they were all useless to him, couldn't kill ZZX because all he could see was the boy he raised, and loved. For the first time ever, Marquis loved.
rewatched the ZH XAT scene of ep 26 damn. The emotional tug on ZH's face. His mind tells him not to trust her, but his heart listens to her. Xiao Zhan's acting is SO good ah.
Agreeing to the comments here, ZZX is not trustworthy anymore. I feel a bit sad since i liked his character, but i feel he is gonna choose to side with his father instead of ZH. Maybe at the end that will lead to his suffering.
