I freakin love this manga, there is something really really appealing to me with this kind of storyline. I don't know why I find blackmailing for sex super hot but I do, the forceful pursuit really gets to me. Best of all I like the honor student x delinquent relationships that doesn't start of completely willingly from one of the parts.
Poor Masumi I just want to hug him and prominenta everything will be alright, poor porr thing <3 So sad and tragic, I'm all heartbroken! ╥﹏╥
