So I read this manhwa quite a long ago, I forgot the title so help me please, the story goes like this :

A regular Korean female died after reading his favorite novel, (her favorite character is the female villain, but sadly she died in the novel.) so when our MC died she got isekaied to her favorite novel as her favorite character (her unnie), the OGmc is a badass and just poor souls that ignored by the family, our MC able to meet and talk with his favorite unnie in her dream, she will see her unnie memories but every time she sees her unnie memories she will chough blood and unconscious, so everyone think she is dying, but actually she gets healthier every time she got her Unni memories.(づ￣ ³￣)づ

Lately, I have been really into webtoons with backgrounds like Games, Reincarnation, Level Up, and Dungengon or you can simply say webtoon like “I level up alone”.. there is a long list of webtoons that I have read from webtoons that have 100++ chapters to webtoon that just come out like 15/20 chapter, and now I come to the point that I have nothing to read anymore.
So pls let me know if you have good webtoon recommendations for me.
Just let me know as much as you know(〜￣△￣)〜
