Light romance drama with strong chemistry and a happy ending

Hi everyone, I'm looking for a light romance drama with strong chemistry between main leads and a happy ending.

Things I like: - Fluffy feel good dramas - Happy ending - Enemies to lovers - Interesting leads (I would love a ML as interesting as the 2ML in true beauty/Cinderella &the four knights/CLOY) - Cheabol lead

Things I don't like - Love triangle - Two much drama & leads deaths - Fantasy stuff - The two year skip

This is what I have seen: - What's wrong with secretary Kim (Amazing FL! So funny! Loved it!) - True beauty: (I loved the first episodes, but the 2ML was way more interesting than the ML. I left it after ep. 8 because I was bored at the two leads scenes) - Crash landing on you: (Loved it, the leads had amazing chemistry! Also I loved the friendships. But now I'm looking for something lighter.) - King the land (loved it!) - Business proposal (I liked it a lot. But I didn't always like the humour & the ending was a bit meh) - Cinderella & the four Knights: (Loved the FL, loved the first episodes although the second half was not as good) - Romance is a bonus book: (Left it after a few episodes. The leads have zero chemistry, they look like siblings) - Healer: Couldn't finish the first episode, couldn't understand what was happening. Thank you :)
