It starts off with the main character (MC) being transported into a novel where the original story's female lead (OG FL) dies and has about four suitors. After the OG FL dies, the four suitors find a replacement for the OG FL and fight to win her love. After the MC got isekaied, she becomes friends with the OG FL until she dies. At the OG FL's funeral, the four suitors call the MC out for not crying at the OG FL's funeral, and after she tells them off a little while later, she runs away to live life as a commoner.
She thought no one would care if she ran away, but surprisingly one of the guys who was in love with the OG FL finds the MC at her job and says that if she comes with him to a ball, he’ll give her a letter the OG FL left for her. She’s skeptical at first, but then accepts. The OG ML from the novel, instead of loving the OG FL, loves the MC and he has black hair. The MC didn't know, but all the four guys that loved the OG FL looked for her after she left.
