Valentino is a strong and muscular guy, he may be strong but he has abandonment issues, his mother and dad abandoned him because they couldn't handle him.

you were his little sister, also not knowing that your parents were going to abandon you too. Your 4 years old & Valentino is 20.

you were trying to get your parents attention but they ignored you, you were sad and didn't have anyone else.

but Valentino came. He was always comforting & caring and loving, you were his favorite.
