I will try to recommend* some but I think you have watched/dropped almost everything I have.
Last Cinderella- I cannot say much because you need to watch to know with whom she'll end up. but the drama is full of cute/cuddly/sexy moments.
King2Hearts- I see you dropped it but if you feel like giving it a second chance, the romance is really cute. The problem is that political stuff overpower the romance sometimes.
Lucky Romance- Puppy/cuddly love, it takes a little while for him to fall but after he does he's such a puppy demanding poppos and for her to take responsibility for stealing his first kiss xD
Marriage, Not Dating- This one is full of cute and sexy moments. The kisses are reaally nice but they start as a fake relationship so it takes a little for them to start doing the fun stuff xD
Marry Me, or No?- Taiwanese drama. This one has a fake relationship but it's actually the ML and his sister that are faking it because the sister and the FL have a long standing feud. It's super sexy and the FL is one of the most modern, open minded FLs you'll find in drama. She teases him to no end, going as far as getting naked in front of him and him going O.O
MARS- is a very heavy/dark drama but it has many cute moments and the kisses and bed scene are awesome.
Shopping King Louie- Another puppy love. They are both very naive but Louie is very affectionate and touchy-feely with her. He learns to take the lead pretty soon though hehe ( writing this makes me wanna re-watch).
The Girl Who Sees Scents- It's mostly a crime/fantasy drama but they do fall in love quickly and are affectionate. We even get to see some of their married life in the drama which is nice, the kisses are really good, tbh this is the best drama I've seen Shin Se Kyun in.
