It was a novel that started with the second female lead and the second male lead getting married. The female lead was originally dating the second male lead, but the second female lead snatched the second male lead away. At the wedding, the male lead came to pick up the female lead and said that his fiancée was too naughty and had a fight with him. After that, the second male lead ran away and the wedding did not happen. The female protagonist's mother was from a big family. Later, because she liked the female protagonist's father, her family did not agree with her, so she ran away from home. Later, she adopted an adopted daughter, who was the second female lead. The female protagonist was adopted by the male protagonist's family and left. Later on, the second female lead wanted to go to the female lead's family and become a member of the family as the adopted daughter of the female lead's mother. In the end, the female lead's grandfather discovered that the second female lead was completely vain. At the birthday party of the female protagonist's grandfather, the grandfather acknowledged the female protagonist as his granddaughter. At first, the second female lead thought that it must be because she was happy and proud to acknowledge her, so she dressed extremely scantily. The female lead was dressed conservatively and simply. That's all I can remember. Who knows what this novel is called? (I've already asked n times)
