I completely agree with you and understand where you're coming from, but this is how the story is written we can't help it
You are so right! Unfortunately, the majority of us people in the comment section are already too deep into yaoi world and not affected anymore by immoral relationships... I personally blame it on Killing Stalking and Harada-sensei.
personally, i'm into fucked up incest stories ╮(￣▽￣)╭ so ranzou x ikurou is my thing lol but more like in a doujinshi or something. and i can't blame that on any mangaka, i like that from the first incest yaoi i've read (￣∇￣")
what i would like is for caretaker and ranzou to be happy together (nothing sexually), he's the only one that genuinely cares for him. also ikurou away from norihiko.
Why the hell do any of you ship Ranzou with anyone he is a child in the head sometimes he even soils the toilet. He was already used sexually by his father why do you want any character to have a sexual relationship with a child? Kenichi is an adult he should be with another adult. Especially Ranzou and Ikurou they are half brothers for fuck sake. They were both abused by their own father and mother do you really want them to end up together?
