I feel like I'm the only one not wanting Yus as a boyfriend-soon-to-be-husband. He knows her since she is a child. Even if they weren't close, it's simply disgusting that he see her that way now.... They have been raised as sibling... And Lan is way too old mentaly wtf (add the year before her death and the Time she spends as a child here).
There is just so better option in the other male characters.
