Idol Yameru kedo Kekkon Shite Kuremasu ka!?

Sato Itto is an ordinary salaryman whose lingering trauma has left him deeply guarded when it comes to romance. His quiet, uneventful life is suddenly upended when he attends a school reunion for the first time in several years. While reminiscing about the good old days with former classmates, Hebo—a recently retired idol—makes an unexpected appearance. Seeing her instantly stirs powerful emotions within Sato, as she was his very first love back in their school days. Overwhelmed and desperate to suppress his resurfacing feelings, he turns to alcohol despite rarely ever drinking. The consequences of that impulsive decision become painfully clear the following morning. Sato wakes up completely naked, sharing a bed with none other than Hebo herself. As he frantically tries to piece together the hazy events of the previous night, she delivers a staggering proposal: "Marry me!" Now, two individuals who are absolute novices at navigating romance find themselves thrust into the prospect of marriage. With neither possessing any real experience in matters of the heart, this bewildered couple must figure out what lies ahead for their sudden, unexpected union.
