Jimin had been abandoned by his parents at a young age and he was sent to an orphanage.He couldn't really stand it there because his rank was the lowest and he got bullied.Also caretakers were making discrimination against him so in the end he left at the age of 16 to live in the streets.Being just a sapphire,he sold his body every now and then but mostly he got higher ranks to sleep with him in order to manipulate them afterwards for money,especially if they had a family.Now at the age of 22,he's a thief and lives in the middle of the forest which is close to the city,in a wooden abandoned house.
