Here's the summary:
Makoto has been admiring a girl he has seen on the train. That girl is Kotonoha Katsura, and he even managed to take a photo of her with his cell phone. Due to new seating in his class, he ends up next to Sekai Saionji, a nosy, but sweet and sincere girl. As she snoops for his cell phone while talking to him, she discovers his crush and vows to help him until Kotonoha agrees to go out with him. When Sekai finally gets them together, she realizes her own feelings after finding out that the person Kotonoha liked was, in fact, Makoto. While waiting for her train next to Makoto, who was waiting for Kotonoha, she has him talking about how he can repay her for all of her help. Before leaving for her train, she kisses him and cries when she boards the way home. Kotonoha happily arrives for her date with Makoto shortly after. With all three main characters carrying different expressions on their faces, the story begins.
What's unique about this visual novel is that the whole thing is animated. However, there's not really much movements going on besides the mouth moving when they're talking. Still, it's kinda neat since it's like watching an anime. Although, one thing that bothers me about this is that the clips seems to loop. I don't know if it's just me but most of the clips seem to loop or something because the mouth movement and the voice acting seem to be out of sync. If it weren't for that then I'd say they did a pretty good job with the animation.
Like all visual novels there are options that pops up throughout the game and the choices you make affect th ending. In this game you can either stay loyal to Kotonoha or treat her like garbage and ditch her for Sekai. There's a little bar at the top of the screen to show you how your relationship between Kotonoha and Sekai are doing. There are also plenty of routes in this visual novel. However, most of them become really repetitive with the only things changing are new H-scenes and the ending. Some of the endings don't even have much of a difference from another one.
In the beginning of each run there aren't really any H-scenes in chapters 1 and 2 there's a couple from chapters 3 to the end. I usually just skip them though. If you want to play this visual novel but don't want to see the H-scenes it's possible to just skip them. Not to mention it's really easy to tell when one is going to pop up.
There's a replay gallery included in the game too but the only scenes that are really available for replay are the H-scenes. I would prefer it to have the endings too but they don't.
Overall, I think this game is fun to play during a couple of runs but it becomes boring afterwards due to the repetitive scenes. If you're a fan of Hentai though I'd say this game is one you should play. All the H-scenes are animated.
