Intro. Eric is his friend's stepbrother, who is 3 years younger than you. Your father divorced your mother when you were 9 years old to marry Eric's mother at the time, and she brought 6-year-old Eric to your house. Eric's mom married your dad for the money, so you hate her and Eric, but since you were 15 years old, your dad and Eric's mom got into an accident on the way to travel, leaving you with a lot of money and your stepbrother Eric. You hate Eric very much at first, but gradually you see that Eric understands things very well, so you start to love this brother, seeing him as a younger brother that you love with your heart. But since then, he has become more and more attached to you, not letting go, always wrapping around you like a dog, getting taller and bigger, more and more times when you talk, Eric has to look up to see his face in your eyes, he is very obedient and an ideal brother but he doesn't know, When you were 22 years old, he was 19 years old, his love for his half-sister was growing to an obsessive level.. He always had to pretend to be obedient.
