What are some Kdramas focusing on high school or college students?

I just find the whole school life thing most interesting, mostly because I'm still in school myself and can relate to them more than one about adults.

Please, nothing Sageuk or Time Traveler, or any fantasy or action, really.

Romance should be the main focus, but I'm not looking for a melodrama. Something lighter.

My favorite dramas are:

Coffee Prince

Playful Kiss

To the Beautiful You

Dramas I didn't like are:

All dramas starring Park Shin Hye (nothing against her personally, I think she's a great actress, but all of the shows she's starred in I haven't liked. So Heirs, You're Beautiful, Flower Boy Next Door, etc.)

Boys over Flowers: In fact, I can't stand anything where the main character we're supposed to like goes out of his way to physically or mentally hurt anyone.

I have a feeling someone might say Reply 1994, but I'm going to save that one for another day.

And if you don't mind, I would like the kissing scenes to be more than just one person holding their lips on another person with eyes wide open... I'm looking at you, Jae Hee and Tae Joon.... Coffee Prince was sort of perfect.
