UGHHH I LOVE THIS AUTHOR SO FREAKING MUCH.
Anyways, Officeworker Uke x Mafia Related worker Seme.
Seme got time travelled to the future, met uke by pointing a gun at him and asking to go to his house. Cohabitated together. Had smex of course HAHAHAHHAHA
All in all, no any other extra peeps to either ruin the relationship of the main couple or annoy the fucc out of u. :)
