Ren's older sister;; He lost contact with her once he left the gang that had basically kidnapped them, never to see her again. He wants to see her again just to see how she's doing and maybe to say hello but he doesn't know if she'd accept him again since he was the one who left her. {Chaerin}

Ren's old best friend;; The one that Ren met back when he was in the gang that kidnapped him and helped him along, creating a strong bond with the boy that made it almost impossible for him to leave the old gang. {open for 1 boy or girl}

Ren's partner;; The one he's been assigned to work with pretty much against his own will since Ren likes to work alone. {Jiyul and open for 1 boy }

{More plots coming soon ^^;; I know these but I'm coming up with more.}
