Dust kidnaps Classic who gets scared. Dust thinks of ways to calm him and he grabs his soul and starts to bite and lick it, making Classic feel strong pleasure go through his body. This makes him more scared and starts to cry and Dust stops touching his soul.
He went to Classic to hug him and he calms him down. Classic then asks him why he kidnapped him and Dust told him he loved him and wanted to keep Classic safe.
Classic gets a bit disturbed by this but nods and from there, Dust tried to keep Classic as happy and as comfortable as he could as Classic was kept in his basement.
Classic started to slowly warm up to Dust and soon got Stockholm syndrome for Dust. He would blush everytime Dust went to him, fed him, bathed him, ect.
Dust kept Classic's wrists chained to the floor so he couldn't run away so he did all the caring for Classic like feeding him and stuff.
Soon, Classic confessed to Dust that he loved him and Dust wanted to make sure that he was telling the truth so Classic agreed to show him. Dust unchained him and Classic got on top of Dust, Dust knowing what was going to happen.
After their lemon time, they become lovers and have kids :D
