STORY (10/10)
The story was very very well developed. Unique idea portrayed very well without any confusion. Actually the flashbacks masumi gets in the library when he meets ritsu was a little confusing for me since i didn't realise that was his flashbacks i actually thought it's the continuation of what happened in the library but then later i got it and it was smooth since then.
At first i did feel like it was a little rushed for all the romance and sex because i didn't expect the tables to turn so quick Ofcourse I HATED Ritsu in the first few episodes he was a total jerk. and i should say that actually paved the way for such an amazing character development. I loved all the characters and how we got to know each of them in depth.

ACTING / CASTING (10/10)
okay trust me on this, absolutely priceless acting. This series sure offered splendid acting skills and such amazing portraying of emotions. You can really feel their emotions through the screens even without a single dialogue. Just simple glances and movement of iris are enough and the cast has payed attention to all the details they should cover and deliver as beautifully. One thing i always have in mind is, if any actor can deliver beautiful kiss scenes and sex scenes, they are god gifted actors. (personal opinion no offence to anyone or anything). The kiss scenes were so beautiful and tender and the explicit scenes got me GASPING FOR AIR!!

MUSIC (8/10)
The music is actually very good but am not someone who pays attention to the music in a series so don't take my rating on that into consideration.

REWATCH VALUE (9/10)
Just because I think you won't get the same feelings when rewatching since u already know what's up and again personal opinion don't take it into consideration if u don't want to.

OVERALL (9/10)
Wonderful series with an amazing storyline, great character development, wonderful production, acting and smooth delivering as well as pleasing filming excellence!!!
