The story is unique in bad way like NTR .Not sure what to think or do. this manga is surely depressing the audience. main fault is that the Female MC of this manga doesn't care about the feelings of Male MC. She know how he feel about her despite that she did S*x with every man who forced into her without trying to resist.
I'm so depressed now I can't write anymore details.
Suggestions if you're strong willed person then don't hesitate to read it.
But if you're weak or average or normal willed person then pretend like you had never scene this manga.
