Bringing her best friend to her boyfriend's house was probably one of the stupidest decisions in Kawakita's life. Her complacency and lax attitude must be what she deeply regrets, as it cost her not only a friendship but also shattered her love. As soon as she saw her friend's boyfriend, her best friend quickly started to have lustful thoughts because he was not only tall and handsome, but also well-endowed. Naturally, with her sophistication, voluptuous body, and incredibly seductive moves, there was no reason he wouldn't be captivated by this cunning girl. It’s a pity for the girlfriend, as she hadn’t reaped any rewards before her best friend blatantly stole them away.
