Kdramas where the couples get separated?

I want to watch kdramas where a couple meet as kids or teens, and then something happens which leads them to be separated. Then there is a time skip where they reunite as adults. The ones below are the ones I have watched already. Thanks!

-Wild Chives and Soy Bean Soup: 12 Years Reunion

-Shark

-Love Rain

-My Love Eun Dong

-Innocent Man

-Autumn Concerto(I know its not a kdrama but its amazing!)

-Missing you

-King of Baking, Kim Tak Goo
