Takayki is a lazy high school student who just flows through life without a plan. One day his friend Mitsuki tells him to go to a local hill after school. Instead of meeting Mitsuki there like he was expecting, Haruka shows up and asks him if she would be his boyfriend. After wavering for a while he agrees and the two start dating. Mitsuki wasn't entirely honest with Takayuki as it appears that she has feelings for him as well
