Eiko is working part-time at a certain company and does miscellaneous duties. One day, a full-time employee named Kyoko invites her to a drink after work. Then he was taken to a certain izakaya where Kyoko's mother, Izumi, serves as the owner... A few days later, Eiko visits Izumi's restaurant again and has a relaxed atmosphere and ends up drinking alcohol that she doesn't usually drink. And as expected, I was overcome with sobriety. Eiko didn't know about it at the time...the cleverly organized traps between Taizumi and Kyoko...
