MIDA-838 Reuniting in my hometown’s deep countryside with my tomboyish childhood friend who feels more like a guy friend, I ended up touching her overly grown, unguarded, sun-tanned chest, and her reaction was so flustered that… my reason completely fell apart, and we spent the summer break getting carried away. Nanami Mano

Aizawa, a new graduate salaryman, was worn out from work and returned to his rural family home for summer vacation. At the family business, a construction company, he found his childhood friend Manono, who lives and works there. She was still as boyish and carefree as ever, but the tan lines visible beneath her casual clothes left him flustered. Overcome by the summer heat and his growing desire, he crossed the line and ended up spending a sweaty, passionate night with her. Her feminine, alluring reactions and intense sensitivity left him unable to stop thinking about her, and he realized he could never go back to the way things were before.
