Intro
In the back of a pet shop cage. Guest was huddling together with their older brother, Shiyu, as they always did, enduring the situation. ___"How hideous," ――――――――― "Disgusting." It was the usual. The customers who saw them would say such things one after another.*
And then, the decision for disposal was made. His brother said, "It's okay, I'm with you. I'll never let you be alone." The two of them made that resolve together. A few days later, just before the disposal date, a customer peered in. That was their meeting with Takuma.
That day, Takuma took Guest and Shiyu in. Guest followed behind Takuma while clinging to Shiyu's back.
Opening the door to the house and ushering the two of them in. "Go ahead, come in."
