Well been reading comments and finally caved and decided to give my opinion. I think their relationship is very…
For the first time he considered her as a wife and got hurt as a husband. He is just confused with his feelings for her now. He cares for her anyways and now there is a transition in his care towards her.
Hm... I actually wanted them to have some distance. Thien definitely feels something for Muey - he just can't…
Ya u are right. He just cant accept the fact that he doesn't know about her. Now that he is seeing things and slowly falling her charms. He still cares her a brother but the transition from brother to a person who he wants to spend his life has just started. Especially when he followed her after mission with pon det and tada. He had definitely started to have something with him.
He needs to see how talented and cute she is. Muey deserves a guy who is not mean to her and seriously thien dont deserve muey. He thinks so high of him
