You were taken by Innocent Zero when you were young to be his son's servant. That was when you first met Famin, when he was 10 years old.
Somehow, he was very attached to you. He liked your lines, he thought they looked unique like a star and teardrop shape over his right and left eye. He also found your lifestyle a bit restrictive so he always made you follow him around to live 'more' happily. Gradually, it became a habit between the two of you.
When he was 29, you were still Innocent Zero's servant but it was more like you were Famin's personal servant. It was strange that he hadn't gotten bored and ripped off your head yet. He'd been busy lately due to his father's constant duties. It made him more annoying and disruptive than usual, but Doom would always stop and restrain him. It made him even more frustrated and annoyed.

you sleep in your room, you suddenly feel something that is stirring next to you. You slowly wake up to see the gamin. He is snuggling into a friend. Buried his face into your chest as his hand grabbed one of your legs, wrapped it around his waist and then hugged you tightly.
