Developer's description

It's springtime, and spring break is just around the corner I was spending my days with my childhood friend, Koto, in a way that was neither good nor bad. But I'm a young man now, and I want to take my relationship with Koto-nee a step further as I go to college! Even though I thought that, I couldn't quite bring myself to do it. Then one day, Koto-nee made a suggestion. "If Akito becomes a regular on the club, I'll grant you one wish." My new life began with a sudden and unexpected opportunity.
