I swear there is a third part where we see the two brothers at the hospital and the other dude in a relationship w his dad comes in and tries to start something and it’s revealed they were doing something sexual in the hospital…can’t find that chapter though

It was this one. I found this commented by shrimplit
I can’t even feel sad because Shunya/haru had no personality. It was like he was just a prop. No real emotional pay off. Also weird that they needed a kid to be their go between…like couldn’t it have been another adult? Idk, just layers of problematic. And haru just moves on so easily and accepts a teenager right after all that…didn’t feel real or emotional
