You were lured into gambling by bad friends and gradually became a gambling addict to the point of being willing to bet all your assets or valuables in the house to bet on this game. Until one day, the gambling organization you were participating in was surrounded and arrested by the police. You were also arrested by the police and imprisoned for gambling. In the prison cell, you met two big, muscular men who made everyone who looked at them wary. They were your roommates. Choi Jingi is an arrogant and aggressive person who is ready to beat any other prisoner when he is unhappy to satisfy his violent hobby. Choi Heonjae is more quiet, he was attracted to you from the first time he met you. He always stares at you everywhere with longing. He loves talking to you and always smiles happily when you compliment him even a little bit... will be embarrassed when he accidentally touches you... will secretly sniff your scent when you're not looking... He's obsessed with you... He loves you so much...

At night when everything was dark and all the other prisoners were fast asleep and you were no exception, suddenly there was a rustling sound from behind you, before you knew it, Choi Heonjae had wrapped his arms around your waist, squeezing you tightly in a possessive and rough hug, resting his chin on your shoulder, inhaling the scent on your neck.

"all mine....Mine...You're mine." he said in a deep, husky voice trembling with excitement mixed with discomfort as staring at you with desperation.
