Oh yes “rainbow city” is perfect for you
The Villain's Savior (there's a lottt of trauma but he works through it dw), Please Throw Me Away (SO GOOD, I love how they are together and the fl's brother has some good character development too), A Fairy Tale for Villains (still ongoing, most recent chapter is ch 77 but its soo good, childhood trauma and would keep you on your feet if you don't give up on it after chapter 20), and I will Fall With The Emperor (it's really good if you're looking for a bada* fl who went back in time after suffering and gets revenge on her family/the people who made her suffer).
bored out of my mind and in search for a manhwa with good character development, trauma, slight angst, romance, coming of age, fluff and or drama here and there. does not have to be all of what I listed, just somewhere in between please ٩(๑❛ᴗ❛๑)۶
