Yes, it's his biological mom, unfortunately. In the manhwa(or I don't know if it was manhwa or novel) it was mentioned that Keith's mom ran away from Keith's dad and so the mom would always run away and Keith's dad would always capture the mom and imprison him I guess? That's why since the mom came back there was a party organized. Remember the party where Yeonwoo was vomiting? Yea that on.
PS pls dont ask me how I know I read the novel 5 times.
Can someone spoil me and tell me who that dude kissing Keith at the end is?
