If you're a person who prefers softer and funnier storyline, I wouldn't recommend Killing stalking I literally couldn't sleep after reading that (welp yes I'm emotionally weak)
some of my favourite ones:
Cherry blossoms after winter, it is even filmed into a KDrama rn
Here U are
Big Apple
Banana scandal
Sign
Mad dog
When the Yakuza falls in love
Love is an illusion
Heat and run
How to chase an alpha
Love shuttle
stranger than friends
A guy like you
On or off
I can't think of anything else rn
