Before Su Xuewen passed away, he called the original character to his side and reminded her repeatedly with tears in his eyes. He told her to live well with the male lead and warned her that if she didn't go overboard, the male lead would take care of her and her younger sisters for the rest of her life. Even if she didn't want to have a live-in husband, she had to try her best to let it go for the sake of her sisters.
Unfortunately, the original character didn't do it either.
She had failed to follow Su Xuewen's advice before he died and the detailed plan for his daughters.
