I'm looking for kdramas where the female lead is much younger than the male lead. Maybe she's in high school and he's older or like in her twenties. I've already seen: My Princess My Little Bride Doctors Bring it on, Ghost Currently watching Goblin Prime Minister and I Marriage Contract Hello School Girl Valid Love Coffee Prince Remember, Korean Dramas only please :) I want a feel for the older protective male figure. Kinda like the vibes in the show Goblin
