Even after their child has grown up, the Keimika couple's relationship is as sweet as newlyweds. One day, her husband leaves for a business trip for three days. Naturally, Keimika sadly sees him off, but right after her husband leaves, she starts making a phone call excitedly. 'Hello? My husband just left! I can't wait to see you; it's been tingling down there... Yeah... I'll be waiting.' It seems that Keimika has been enjoying an affair behind her husband's back.
