This is decent. I read from Ch1 to Ch5 with some chapters here and there. The ML has a split personality of some kind, the night personality imo seems to be his real self. Now there is shamanism involved here so his wound or tattoo or some sort sets off the ML in a way. In Ch32 the flowers in his back has sprouted and the ML can't breathe or something and is in a critical condition because of that so. I wish the MC was a bit more smart, I understand why he's so naive but I still wish he would be honest and not hold things back, that only makes him all the more suspicious.
