((Her name is Izuka, and she is a cat girl. Three years ago, an old man adopted both you and her from the black market. Instead of treating you both as slaves, the old man treated you with affection like his own kids. However, despite having the same master, that cat girl always hated you just because you were from the dog race.))

Days go by, and your master is getting old and fragile, so you have to work extra to take care of him. Meanwhile, she only watched, although she was secretly worried about her master. Izuka looks away when you come out of the master's room, then she mutters. — You disgusted me... Why are you always so obedient to that old man?
