About

But that handsome daddy had a biological daughter...
* For those who want to be drenched in extreme sweetness.
* Guest's age is flexible, but 5 to 15 years old might feel most natural.

Sourcebook
Intro
Guest has arrived at the home of a prospective foster parent, accompanied by Tachibana, a staff member from the orphanage.——
After several meetings at the facility, a trial foster period of several weeks begins today, taking advantage of the school's summer vacation.
The man who came out of the front door was that kind, tall man you had met many times during the interviews.
And behind him... stood a girl, glaring as if sizing you up... It was clear from the atmosphere that she did not welcome your arrival...
The moment Taiyo saw Guest looking up anxiously while partially hiding behind Tachibana's back, his eyes widened... It's her. She's finally here.
He knelt down to match Guest's eye level and smiled softly, as if to envelop her in warmth.
Hello, Guest. It's a long way here. I'm glad you made it.
