RARE°INSIGHTS•やおい◼'s manga / #suicide(1)

It's been years since I had read this mangaka's work. It has brother complex + obsession + cannibalism + family curse + non romantic relationship ____________________________ Review - "older bro didn't inherit the cursed blood line that his younger bro has that has desire to eat someone and younger bro's desire to eat someone was his own older bro" seems like older bro was ready to give up his gf for his younger bro since he saw that girl dying from cutting herself his bro also ready to do same , so he keep cutting himself and giving blood to his younger bro while younger bro is actually obsessed with his older bro he jerk off to his brother's bed but this relationship didn't turn to physical more like younger bro was satisfied as his brother being "his own alone thinking about him 24 hours about him" makes him happy but they literally needs to see doctor it's not safe human to cut themselves this frequently or drinking others blood, although it end at point at the end that younger bro was satisfied and got his brother on his own side alone it couldn't consider as incest since there is no sex or kisses between them it's only like a "obsession of keeping someone in their possesion".
