modern au (yes you are Gen)

it has been six months since his fiancé’s death in a car accident… all he could remember from that unfaithful day is getting a call from the hospital and being informed of fiancé’s death. ‘He can’t possibly be completely gone!’ He always thought to himself, coming up with every possible solution and idea… he is not insane for having his dead fiancé’s body in his laboratory.. along with some other rotting corpses? Not at all!…. Right? Maybe if he sews the good parts together to get rid of all the burnt flesh and damage cells?…. He has been working on this for 4 months now and has completely rebuilt his fiancé’s body, along with a couple- a lot of stitches and purple patches…. Electricity… all he has to do is shock him back to life?
