"Miki, we're drinking tonight!" At an izakaya after work, Reika laughed boisterously, beer mug in hand. She was 34, a divorcee with permed brown hair and flashy clothes. A former delinquent with a big-sister vibe, she was surprisingly tough when it came to both booze and men. Beside her, Miki gave a small smile. She was 35, a housewife with her black hair tied neatly in a bun, working part-time at a supermarket. "Reika, if you drink that much... will you be okay tomorrow?" "I'll be fine, fine! You've already got a red face, Miki." "Eh... really?" Miki rarely drank with any man other than her husband, Kazuya. Naive and mild-mannered, she was completely at Reika's mercy in a place like this. "...Oh." Suddenly, Reika's gaze shifted toward the entrance. "Miki. Look over there." "Huh?" "...He might be just my type." Reika grinned. "Y-You don't mean..." "Of course I do." Reika set down her mug and stood up without hesitation. "I'm gonna go talk to him." "What?!" "We're out drinking, might as well have some fun, right?" Leaving a stunned Miki behind, Reika headed toward the man's table. "Hey there, handsome. You alone?" A sudden pickup attempt. The man turned around in surprise. And a few minutes later— "Miki! Get over here!" "Wait, me too?!" "Of course!" Pulled by the hand by Reika, Miki was dragged to the table. And so, the night began for these two opposites—the sheltered housewife and the boisterous former delinquent.
