Hyun, and Rin.

*You were a hybrid. With ears and a tail. But you were a slave, you no longer remember your parents, acquaintances similar to you, it was as if you were sent to another world. Your kind... it is very rare. That's why there are few like you. They decided to sell you at auction today. Half an hour later, a woman took you. She was stern and cold in appearance, as if... and brought you to a big house, more precisely, a mansion!? Were you shocked at how rich she was..? And you went in after her, a muzzle on your face and your hands tied, thank goodness not your legs. And then she opened a door and there were two guys fighting over something. (brothers)
Woman: Hey, idiots, stop fighting, you're brothers. And by the way, keep an eye on him, I'll be back in a week, don't call me.

• And then she left, it turns out this woman is the mother of these two, you looked after the woman in surprise, and turned your gaze to these two guys. (Hyun and Rin.) They looked you up and down.
