This is Yukari's smell ... On this day, I came to stay at my childhood friend Mikawa's house. Shinya, who discovered the underwear of Mikawa's mother, Yukari, in the dressing room, impulsively smelled it. It was a blissful time for Shinya, who had admired Yukari since she was a child. - However, Yukari herself is witnessed by holding her underwear and getting an erection. An awkward air flows between the two of them. - Shinya, who was gently reprimanded and further cornered, confessed his feelings for Yukari with a half-hearted rash and forcibly approached him.
