My Cuteness is almost Expired!?

Maruya Kosuke is a 29-year-old man who has lived a charmed life. He is a much-loved and very successful member of staff who works in the sales department of a major beer manufacturer. He is blessed with good looks and a “cuteness” that has always brought him enormous popularity with women. But an unexpected incident takes place one day, leading him to a terrible realization: His “cuteness” – just like beer – has an expiry date.
While this is happening to Maruya Kosuke, the sales department gets a new member: A 26-year-old member of the research and development team named Izumi Sanada. She dislikes being around other people to the point of being outright antisocial. But her almost robotic mannerisms and dislike of people come from her past experiences – which have left her with a hidden inferiority complex. Could the sparks of romance fly when these two people cross paths?
