I go to a relative's house in the countryside during the summer vacation. A cousin's older sister who reunited with each other for the first time in a long time with the faint memories of her childhood in her heart. Hold my tense hand and gently repeat the kiss. A hot day in the middle of summer, when the body was superposed on the uncontrollable urge. It all started with the sweat that blew out, the luscious body that was wet and transparent, and the sudden heavy rain that sheltered at the bus stop.
