I'll be honest, the characters in this mănhwa is kinda unlikeable

hyesung need therapy

It’s the author’s talent to make unlikeable characters but you still remain curious. I think they’re too good at the subtle humor throughout that makes the story more bearable

Just finished it, im kinda happy that at last they changed and tried to change. But I wouldn't be caught being of any of them before their change in personality.
Hyesung still need therapy tho.
