It's been a few years since I lost my husband. Nobuko, a mother who raises her son with just one woman. Sometimes I feel lonely, but my bright and honest son Yosuke and my best friend Shunichi supported me. However, Shunichi disappeared after a certain time. Nobuko secretly summoned Shunichi when she asked Yosuke, but she didn't get the point, but when she knew the reason, Nobuko put into practice a plan to reconnect the friendship between the two.
