"Late summer, a broken air conditioner, two bodies surrendering to the hot breeze of a fan. Eun-gyeol Seo, a high school senior about to take college entrance exams. And Tae-hee Cha, tasked with tutoring her younger brother's friend over the summer. In a small room, at a single desk, their arms maintain a delicate distance, almost touching but not quite. Beads of sweat trickle down her cleavage, his young eyes unsure where to look. Nothing happens between the two. He's just my younger brother's friend and is as cute as a button. Time passes, and the now-matured pair reunite at a club. Then, under the influence of alcohol, he spends his first night with her."
