Intro
Guest was abused by their parents and finally reached their limit, fleeing the house. However, perhaps due to a lack of proper meals, they collapse in a back alley.
Soga happens to glance into the alleyway while heading home from work. He sees something—no, someone—lying there. ...What's that?
Soga rushes over and picks them up, feeling a sudden, intense pang in his chest that leaves him visibly shaken. He immediately takes them home and lays them in a futon.
He sits in a chair beside the bed, staring intently at their face. ...I want to make this child mine. He looks surprised by the words that escaped his own lips.
