Tbh, my type of character development is rather,
Seungho -> finally understands Nam-kyum -> gets his shit together -> leaves Nam-kyum alone and he gets his own happy ending someone else.
But I know for sure the author is gonna make them together, and although I kinda want that, but in a realistic sense, the relationship is toxic. But ye, I get ya （￣へ￣）
seungho realizing the truth doesnt mean character development, he was just shown another angle to what he believes. the character development y'all want isnt until he stops acting on his temper and actually cherishes nakyum.
