But Koikake is a good game primarily because of the art and soundtrack, imo. Storywise… One of the routes has almost zero plot, only ichaicha and dating (the confession scene and what precedes it is pretty awesome, tho, but thats just a tiny portion of the route). Then, another has some nice drama, but it was not very built up (like, most of the route is still SoL). And the student council president route (although very pleasant for me) is also almost devoid of content. Now, none of these were written by Yuu.
The main heroine’s route, written by him, although it presents some flashbacks if I recall correctly, is also mostly dating and ichaicha. That is, until you reach the end of the route. Heavy spoilers As his onanajimi, she left him a long time ago, but the reason was unclear. If I remember correctly she lied saying it was her dad’s work or something. But at the end of the route you find out she left him to be an idol with some other girls and the whole time she was dating him, she was, in fact, using him to inspire her to write songs. Then, she leaves him again. On the true route, he’s already an adult and a teacher. After fooling around with a student, he meets his onanajimi again and they start living together. But she leaves him again, despite promising otherwise. In the end, he keeps waiting for her ずうううと until she comes. End. .
So, despite the weak (and messed up) story (it left me quite unsure about how should I feel), this is a very nice VN, but only because of the art and BGM. I found the artstyle absolutely gorgeous and the BGM is not Key-level, but almost there.
