It's a yaoi manga about soulmates. I read it before but forgot to mark it, and I want to reread it again. People have soulmates and can write things through their body and it can appear to their soulmate's in which they can communicate. The ml ignores the drawings in his body that his soulmates draw since they're little because he hates(?) this soulmate things. Then one day the drawing stops and he went to look for his soulmates.
