Maybe:
A Tale of Thousand Stars (meaningful, beautiful, flirting while bickering)
Bad Buddy (friends to enemies to lovers, super sweet)
Be My Favorite (less romance but the chemistry is great though at first it's all bromance)
Dark Blue Kiss (not for everyone as ML (Tay Tawan) is controlling and domineering, but for me it's a perfect 10)
I Feel You Linger in the Air (full of romantic skinships)
Last Twilight (slow burn but really sweet)
To Sir, with Love (less romance but the chemistry is great, full tension)
