カテキョしちゃお！ ～ひとつ屋根の下、むひょひょ合宿物語～

I've always barely been capable of studying, even from a young age. Although I somehow managed to make it to college, I could not keep up with the level around me, and my grades were on a downward spiral. My family, who were worried about me, suggested that I give up my summer vacation and improve my academic skills. My sister, her friend that goes to the same college, a senior, and my highschool teacher also came and stayed at a cottage in the countryside and it turned into a full-on training camp! Under the same roof, a month-long cohabitation with the older women has begun!
