Kei Wataya, age 28, is an unwed single mother from a small town... whose beloved son refuses to go to class. The pitying looks she gets from her fellow clinic staff, not to mention the rest of the world, are almost bad enough to make her wince. Between work and trying to help her son integrate into school better, Kei's got her hands too full to worry about romance... and that's assuming anyone would even be interested in a woman with so much "baggage." That's where 40-year-old doctor, Nagisa Kamijo, comes in. He's more than a decade older than Kei, and his disparaging view of women is just one of many reasons they don't get along, so there's no danger of love blooming between them... Or so she thought, until a bizarre proposal from Kamijo lights a spark that might just become more. She couldn't care less about love or romance, and she doesn't regret the life she chose, but some nights she yearns to feel the warmth of another body... Tune in for an age-gap romance just as off-kilter as it is passionate, between a single mother who's "done with men" and a doctor who "hates" women. (Source: MangaPlaza)
