It's really fucked up but strangely I understand ukes point, sometimes kids are really cruel and they do absurd things that they end up regretting, there is no explanation or justification it's just "life".
I'm soooo confused, everything is going so fast, the plot is a total nonsense, it's so messed up that the "shota thing" is not even the main problem of this manga( ̄∇ ̄")
It's as if the artist said "hey, why not do something without any logical sense with big titties and a lot of porn without plot?!" ╮( ̄▽ ̄)╭
