Major spoiler below so don't blame me after reading it
His death made me the saddest and I hate that even in the alternate timeline he still died... I get that he is old but seriously, I didn't want to experience that twice. I love his character so much.
jinwoo's exchange ability really showed
1. the fact that he's literally a tree cause he's so much taller than he was in s1
2. the eminence of a shadow monarch [AND]
3. hunter cha's "attraction" to jinwoo
side note: the association president is too good...i love his personality
