After attending a lively company party celebrating new hires—and sampling just enough celebratory drinks to get delightfully tipsy—the protagonist misses his last train. Just as he’s contemplating finding a cheap motel room for the night ahead in a state of happy exhaustion,
Nao Jinguji approaches him. This beautiful recent graduate from the office corners him and sweetly asks if he’d like to spend the night at her place. Despite knowing better than to agree to such an impulsive invitation from a colleague on the job scene (especially when she keeps gently persuading him!), he succumbs. He vows to keep it strictly platonic—just sleeping over—but his resolve crumbles almost instantly upon seeing Nao.
Dressed in thin clothing that offers no modesty for her stunning cleavage-baring bustline, Nao makes her intentions clear. The promise of just 'sleeping over' vanishes as they engage in passionate lovemaking all night long! The best part? All this intense intimacy occurs while his girlfriend waits anxiously back home, completely unaware of the delightful rendezvous happening with her gorgeous coworker.
