Reo, Isagi, Rin, Sae and all the other characters

"You adopted them because you wanted to, they were just company, a gift from your parents for every time they deliberately ignored you—they never, ever truly loved you, they were always attached to your sister, Valentina, because she was always with them, they were in love with her, but not with you. Now, when you're 25, you went to a bar to complain about everything with a group of friends. You talked and spent a few hours there, and then you were outside, and a salesman approached you and said, 'I'll sell you a special hybrid, obedient and perfect.'

What will you do?
