Welp.. This was one of the things I read when I was deep in the incest trap. I still am to some extent but I don't seek it out now (only in fiction btw since I like taboo and controversial issues). I was pleasantly surprised by the exploration of the lil bro's inferiority complex and his blind devotion to his big brother. I'm glad they addressed that in this manga, it sticks out from other mangas in the same vein as this because unlike the others, this actually tells us the ins and outs of why he feels this way. In addition to that, it also sheds light on how this relationship affects their life outside their little twincest bubble. The big brother is very interesting in hindsight.. He never thought of his lil bro like that but he didn't seem to mind it when he found his brother touching him.. Since he felt good. This sentiment is also shared by the seme..he thinks to himself 'this is how nii-san has always been, he just goes with things that give him pleasure or satisfaction'. He doesn't think or function like the normal person. The idolization part also fascinates me. I love the drama aspect of it too and like the thought of other people regarding their dynamic.. Even his(the seme) friend comments if it's not tiring wiping his ass for him. I also love how this extends over to their adulthood when they move out or go job hunting and not just students. It makes the story more solid that way. That's all.
