Heyy I hope I can help you a bit with my recommendations :))
I mostly watch Thai ones tho. But I hope you find sth you like :D
TharnType (Currently airing)
2Moons ,2Moons 2 (The second season has a different cast but they're much better in my opinion )
Dark Blue and Moonlight (Loved this one) - Taiwanese
Long Time No See (They had a low budget to film but it's VERY high quality in my eyes)
LBC (alot of people loved it; I think it's okay)
My Dream (Really cute)
Pornographer (This one is... different; If you aren't alone you should maybe watch it with headphones...) - Japanese
Sotus (There is a prequel too but I didn't watch it yet)
Theory of Love (Cute and funny)
Together with me (there is a prequel too; One of my fav's bc of the chemistry between the two actors wether it's on or off stage)
Waterboyy (the drama version; the movie of this came out first but I liked the series much more)
