Woman reincarnates into one of her favorite books/novels/manhwa, her favorite character is second male lead. She lives her life in the world watching them play out the scenes until they reach the happy ending (for the main female lead/male lead). After the main story ends, she realizes that the second male lead, her fav character, is so depressed and constantly trying to k!ll himself. So she brought her to her own house to try to take care of him but that is when he actually ends his life. She gets so upset from the story and how he never gets his happy ending and she gets reincarnated again and this time she doesnt sit back and watch she decides to go marry the second male lead to see live a happy life.
She also uses her knowledge of the story to be able to "look into the future" and uses this to win the trust of second male lead and first male lead (prince).
Thats all i remember from this manhwa if someone can help me find the title
