So suspicious........

First let's talk about how the MC is constantly subjected to mental torture, however, the first crash out we witness is over a painting. And then, is the pink-haired guy a sorcerer or god in disguise or something, since his sorcery is so skilled and undetected, and he had a smell this god had never smelled before? And is the MC a reincarnation, clone, or similar replacement of someone? The god said he'll keep him until he's tired of him, but he's also obsessed and looks like he's looking for someone in him. They said the god nurtured him, and I don't know how early in the MC's life we're talking about. I need his and pink-haired guys past asap, but I also like the slowburn
