A single man in his thirties living near Shin-Maruko Station along the To○ Line. He frequently visits a girls' bar in neighboring Musashi-Kosugi, where he's particularly drawn to Chinatsu, a cute-faced, big-breasted girl with a soft, gentle charm. When she asks, "Can I have a drink with you?" he can't help but agree and orders a round. Spotting Chinatsu after a night of drinking during the morning commute, he impulsively starts secretly filming her. When she says she's still not had enough to drink, they wander through the bar district and eventually, near Maruko Onsen, he suggests, "Wanna keep drinking at my place?" To his surprise, she cheerfully replies, "Sure!" The girls' bar worker, still tipsy from drinking all night, finds herself completely overwhelmed by what follows.
