So it's a straight manhwa where ig the MC girl returned back to the past. Idk if her brother is still alive or not ig he died. So in this manhwa there's like powerhouses like her family has an emblem of black house and her family is very ruthless. She has and elder brother who wouldn't wait to kill her he had black hair also she has younger brother who also had black hair. So she is determined to kill the father and she secretly becomes stronger. She has blonde hair and red eyes and she has abilities like controlling blood sucking butterflies or so. The male lead has blue hair, he is of another house with blue emblem. So he becomes the prison the MC house but MC secretly helps him run away and later on he brings in the army to defeat the father and later on the MC kills the father. I CAN REMEMBER ONLY THIS MUCH.
The MC bottom is reincarnated in a novel like story, where the ml was supposed to marry MC and later on kill MC upon finding the lead of that novel but after MC reincarnated the ml started loving him. Also MC is very weak and spits blood from inside. Also there's like another person pinning on the novels' MC, and they are like in the same group project
Gloomy delusion
