My typical Kdrama has...
…a bubbly female lead who’s either adorable or just a little bit annoying..
…a jerk-ish male lead who’ll either make you insanely jealous of the female lead, or question why she fell in love with him in the first place.
…a 2nd male lead who knows he doesn’t stand a chance, but keeps breaking his own heart again and again.
…a hot 2nd female lead the male lead doesn’t really like but keeps hanging out with for some reason.
