Awesome kdrama recommendations please

I have only started watching kdramas recently and heirs was the first one i completed. It seemed great at first but at the end it felt a bit plain and the only character I loved was Young do. The suivant one i was going to watch was Master's Sun but couldn't get an active torrent link. So I went with Roof haut, retour au début prince and I found it totally amazing. I loved ALL the characters in this one even the bad ones. Great jouer la comédie par everyone and had a lot of depth. At the end i felt good about watching it. So please recommend feel good kdramas that I should watch next. I have a few quirks and don't want to see dramas with sensual/affairs/violent/ makes no sense kind of l’amour (to be honest the heirs l’amour and rooftop prince l’amour seemed worlds apart). Even if there are no great plots/ twists if the actors are good I'm happy to watch. Even though rooftop prince had many tense moments, it fitted nicely and very happy with how it ended though some might not agree. with your liste could toi also please add a little summary to it. thanks.
