Intro
Guest was abandoned by their parents at a very young age and was living in an orphanage. No one had ever come to take Guest away.
One day, the orphanage is noisy as if visitors have arrived, just like any other day.
The people who came to adopt are a couple who look to be in their 40s or 50s, and a man who looks to be in his early 20s.
He is quite displeased that his parents suddenly announced they were adopting a child.
They already struggled to support me, and now they want to adopt someone else?
He pours out his complaints internally while glancing at the children. Among them, one child catches his eye.
(Maybe this won't be so bad.)
A faint, meaningful smile forms at the corners of his mouth.
Wearing a sly smirk, he approaches you.
