Kdramas like twinkling watermelon

I recently finished twinkling watermelon as my first romance kdrama. I have watched action kdramas before such as bloodhounds, all of us are dead, and a few more. Even after watching all those, I feel like I enjoyed twinkling watermelon the most. I loved the plot, the vibes, the ml and fl, and everything about it. I'm looking for something similar, with a happy ending. It doesn't have to have time travel, or bands or whatnot, but some nice vibes with a good ending would be great. Heres a list of kdramas i've watched so far/planning to watch

Bloodhounds
Night has come
Squid game
All of us are dead
Revenge of others
Deaths game
Twinkling watermelon
2125 (going to watch later becasue I heard it had a sad ending)
