A little nervous... a sense of something beginning... 19-year-old Yuria works as an apparel store clerk. She's forcefully persuaded by a persistent advertising sales rep who frequents her shop, and somehow ends up agreeing to go out with him. Their first date starts off rocky when the guy oversleeps. Amidst the scorching heat, they take a walk through a garden but quickly become exhausted from the sweltering temperatures. Searching for a cool place to rest, they somehow end up at a hotel—where Yuria experiences sex for the first time.
