It may be bitter pill to swallow but su-ah is possessive abt juhyeok that he wanted to pregnant him and we can clearly see that where actually Jhk happiness lies , he wants to prove something to the world and he will do it for sure ........even the ahjussy is proving the point of him being the biggest fan boy by supporting him in every way without any ill intention (hope so it is the true case ) ,........su -ah u gotta do better than be just sulking and be possessive
If y'all can't handle stories with character who are driven by mental health problems / trauma then please leave, the author's previous work are more complex and dark than this one. There are way many stories out there which would suit taste
Maybe if you were in young place you would have chosen ur golden boy, but remember this young's story, we are only the reader. Not some judge.
