Mieko works at her dream job as a wedding planner and is about to turn 30. Unfortunately, not all is rainbows and unicorns as she constantly feels pressure from her friends and mother to get hitched herself. When she gets teased at a company dinner for being single when two of the younger girls at the office just got married, she begins downing glass after glass.

Seeing her in her inebriated state, Shuji, her young yet reliable (and not to mention hot) coworker offers to take her home. Once they arrive, Mieko's loneliness reaches its threshold, and with her inhibitions already dulled, she does the unthinkable! Come morning though, when the guilt begins to settle in, Shuji proposes that they move in together once he graduates college! Should she feel joy? Should she worry about their age gap? What's a woman to do?!
