It's a nice, entertaining game. Unfortunately, I don't understand why you can't have a happy ending here. I've now played it through twice, each with a relationship with Ichiru and Masaru, and only focused on one of them. But in each case there was only the bad ending. I also think it's a shame that you can't enter into a relationship with the coach.
What I find just as strange is getting the medals to unlock the scenes I have already seen. Somehow I didn't understand the principle. In summary, it's a nice, entertaining game, unfortunately without a happy ending, or if so, I'm too stupid to find it.
