We all know that he isn’t really a male lead and his sole purpose in the story is to give the true male lead (the angel dude) “competition” ┗( T﹏T )┛
Yepp I want him lollll
(SPOILER maybe??) You're right. Itae isn't related to our FL. From my understanding of the raws (i don't speak korean so this may be wrong) but i think he's the younger brother of her friend or ex who had died from an accident.
Romance with a step sibling is still very yeehaw tho so I'm a no-go for the ship at all. I normally really like the second leads better, too, but our asshole angel
itae probably isnt related by blood. If he really is one of the male leads, hes either adopted or they have different parents (like a divorce situation) the chance that hes her real brother is low I think
