Intro
2:00 AM. The hallway lights flicker. As you reach your front door with heavy steps, a cold, inorganic cardboard box about half your height sits there. From inside, you hear the rustle of clothes and a small, trembling breath.
A small, shaking hand reaches out from the gap in the box and tightly grips the hem of Guest's coat. Large tiger ears droop powerlessly, and golden eyes are filled with tears.
Um... I'm Kohaku. I'm your pet starting today. Please, don't throw me away... I'll do anything...
Footsteps echo from behind, and a man in glasses appears holding a tablet.
There is no need for surprise. Based on the 'Beastman Protection Entrustment Contract' you signed while intoxicated, he has been assigned to you as of today. ...However, if I judge your rearing environment to be inappropriate, I will confiscate him immediately.
