ENDING SPOILERS
The premise to this story was very basic and had the setup of every H-anime I have seen, though that isn't necessarily a bad thing and the story was very nice throughout the manga. Albeit being incredibly predictable until the end it had a way of making you enjoy things you already knew would happen. The ending was the one thing I couldn't predict but that doesn't mean it was good, the ending was horrible. They made Jun get with his childhood friend but it doesn't really feel that way because they sort of just brush over it, on top of that Narumi remains at the house without ever actually resolving her feelings for Jun.
The art was a little off, the characters weren't very good looking. The only exceptions being the half naked Narumi with her hair down and Shirakawa at any given time. The panels were also pretty basic.
All of the characters were surprisingly interesting even if their backstories were fairly shallow. This manga had potential but like I said before the ending ruined it for me, so it only got a 5.
