I also like these kind of dramas so i'll give a relatively long list. I hope you can find something you'll like :)
Firstly, almost all Thai lakorns have lots of misunderstandings and jealousy.
You should watch
Kleun Cheewit asap. It's exactly what you're looking for and you will love it so much. The chemistry between the leads is unbeatable and they have really big misunderstandings and problems but they still fall in love desperately. It was a masterpiece.
And
Kiss Me is another good one. Girl dates and even gets engaged with another guy because of the male lead's behaviours. Ending was awesome in this one.
A Love to Kill is a Korean classic with a lot of misunderstandings, huge mistakes and a big love story. The cast and their acting skills are awesome too.
Another Miss Oh - Not exactly what you want but has misunderstandings and big mistakes between lovers and it's one of my favorite dramas. Great acting skills and "real" kisses.
Fated to Love You (Taiwan version) also has big misunderstandings and the main girl dates another guy because of them.
Full House
Thailand and
Korean versions. Story is the same but Thailand version is better. Same actors with Kiss Me so the cast is really good.
Goong - A classic again with a lot of misunderstandings and big mistakes. No happiness between the main couple till the last 2 episodes.
Innocent Man- Revenge themed drama but turns into a big love story with a lot of misunderstandings and some serious unforgivable mistakes between the main couple. One of my favs. Plus you will see Song Joong Ki and Moon Chae Won, so the drama itself is an eye candy.
Muean Khon La Fark Fah (2017) - Big misunderstandings at the beginning and later big family problems.+Jealous male lead. I really liked this one.
Tangpan Gammathep- Exactly what you want but a really, really old one. But i don't like it much. So not recommended.

I haven't watched this one but i heard that the story is exactly what you're looking for so i'm adding this one too.
