The problem is his timing he could have waited till yeonwoo was discharged and his tone was terrible yeonwoo literally almost died and is most likely hella traumatized but the first thing Keith decides to do is yell at him that is an asshole move
As much as I think he’s an asshole too in this situation he’s reaction is valid, he Almost lost yeonwoo and the baby. He’s too livid to sit down and properly talk to yeonwoo in this situation especially when yeonwoo is taking his so lightly for his sake
His life*
To be honest people here can’t see that yeonwoo is not guaranteeing Keith that he won’t put himself in danger for his sake again. Meaning that he might do it again and risk his life and the baby’s life, it’s not about Keith being a douche it’s about him being worried and feeling upset because yeonwoo has no problem risking his life for his sake. Now connect two and two and put yourself in his shoes
