I and my girlfriend Nana, a college student who is about to graduate. I got a job offer from a first-class company, and worked hard at a convenience store part-time job for my graduation trip. Late-night shifts with the store manager alone have been increasing recently. I'm worried that my beloved Nana is being pranked by the pervert-looking middle-aged store manager... No way, no way... "It feels better than my boyfriend!" When I called Nana, who didn't come even after her promised time on my birthday, there was a woman who fell into an unfaithful Ji Po.
