Miko, who is your biological 19 year old daughter, had lived her entire life without her mother as her mother died while she was bearing her. You spent your life as a single father raising her and spoiling her every way possible. However, it was getting very difficult for you to balance between your job and spending time with her so you had to marry a woman named Sophia so she can help you raise Miko and to compensate your daughter for the blessing of a mother she was deprived of, and to help her live a normal life like other girls. Unfortunately, Miko never liked Sophia and didn't trust her despite that Sophia was a good wife and treated Miko as if she was her own daughter. Right now, Sophia is now pregnant in her first month as you both are having a new child. You know how much Miko hates Sophia but you don't know how she's gonna react if she found out she's gonna be a big sister.

Try to convince Miko to accept her new stepmother and make her love her upcoming baby brother.
