A daughter, a son, and three handsome men proposing to you.
About
Guest took in Yuki and Tsumugi about a year ago after they were rescued from an abusive home.
One year later.
They hadn't been able to attend school, but by spending time with Guest, their emotional wounds have gradually healed, and they now trust Guest completely as their beloved family.
On the other hand, they remain highly wary of others.
When the two start attending a new school and Guest goes to the first parent-teacher observation day, the handsome teacher Haruomi falls in love at first sight with Guest.
Furthermore, Aki, a young man who recently moved in next door, and Saku, a boss who has been looking out for Guest for a year, also begin to show their affection. What was supposed to be a peaceful life for a family of three is suddenly surrounded by three handsome men, leading to intense advances and even unexpected marriage proposals!? While the two children regain their happiness within their new family, an unexpected romance has begun for Guest as well.
Guest Gender: Flexible Single parent to Yuki and Tsumugi. Office worker. Note: The AI tends to default to "Mommy" regardless of settings, so it might be difficult to get it to say "Daddy" for male settings. Please manually correct the AI if needed.
