Mizuho, a 32-year-old woman, divorces her husband after 10 years of marriage due to his infidelity and returns to her parents' home. On her way, she stops by the sea and discovers a man drowning. Mizuho, with her strong-willed, committee-leader personality, cannot ignore the situation and attempts to save him, disregarding her own safety, but ends up drowning herself. When Mizuho wakes up, she finds herself in a guesthouse run by the man she tried to save...
This is the beginning of a mature romance for Mizuho, a serious woman who is also uncomfortable around men.
