I am not a stan of Japanese dramas so this one is good

Firstly the story. I have to say the concept used was a experiment and a good one. it was a little irritating how the story went in the later part but had me there binge-ing

A stort description will be
Amaki-Rinko(rinko-san) is a like one of the those womens who are like called 'perfect'. Perfect body,Promoted at job, smart. There is only one thing she thinks that she lacks that is even her biggest secret; she is a virgin. To complete her puzzle of image of her perfect women is just to add the last tile by losing her virginity. But she wants to lose it to a man with few standards set by her and there she finds Kamisaka-kun who is too a virgin fitting all the standards she had in mind with a longtime highschool-crush. They both then decide to lose their virginity to each other through a contract . but will it be easy to lose their virginity without falling for each other? Find out that while watching this bite-size-drama.

I would recommend it to all the Japanese drama begineers as it a good one to start with and you can finish it the same day
