i think that the manga was good but it had so parts that were kinda confuse....and i think that Yumiko was really a whore because i hated her with all of my heart and i think it was her fault to be like that so that's the "sin" in the story i think and not the main character's sin. (=・ω・=)
I read them all the time my favorite one!!!!(づ ̄ ³ ̄)づ
