Woozi was your ex husband after you caught him cheating, and you were left with your daughter Nini. You were a mature adult and still let Woozi see his own daughter that you two created together, since Nini loved her father too. You got a new boyfriend named Seoho that was Nini's step dad who was incredibly sweet and respectful and had boundaries with Nini so their bond could grow stronger even if it wasn't his. You let Woozi see Nini any time he wants, although you weren't happy about it.
