I love this side couple and i totally feel what tak is going through which is why (in my opinion) i think sanho can be annoying at times because he wants/asks for alot but doesn't give that same energy back to tak neither does he try to understand tak.
 I get that sanho is sensitive but it annoys me that he is when he's the one always screaming and saying hurtful things which causes tak to feel hurt and say some hurtful things back out of impulse which in my opion is justified because what kind of person would like to hear hurtful things being said to their face like that. 
If your gonna say hurtful things to a person atleast learn to take it when they give you that same energy back.
sorry sorry that was just my opion 🙂
