any recs for manhwa/manga that have a good plot with a spinkle of romance ლ(´ڡ`ლ) s...

Did you ask for "Rainbow city"? Cause I think you did. You didn't? NOW YOU DID, TRY RAINBOW CITY (⊙…⊙ )
(SA in chap 3, best to skip)
little mushroom
breaking through the clouds 2: swallow the sea
monochrome rumor
the foul (kinda toxic)
memories of your breath

This is the second time I have been recommended rainbow city to me LMAOOO
I think it's a sign to read it (๑•ㅂ•)و✧

MUST READ, SO GOOD I WANNA SHOVE IT UP MY BUCCHI ITS THAT GOOD ヽ(`Д´)ﾉ

Kono oto tomare
White blood
Faded first love
Death is the only ending for the villainess
Maybe meant to be
Want to see my cat?
Pray to a ghost
Pure villain
The one within the villainess

Read these two in this specific order, tho not a sequel they're kinda connected, also don't be put off by the art at the start, it changes for the better in just a few chapters :

Song of Reverberation
