Kurumi and Keiichirou have been married for a full year after a swift arranged marriage, yet their union remains unconsummated. Both are deeply inexperienced and easily flustered when it comes to physical intimacy, and as their first anniversary looms, Kurumi grows increasingly frustrated by her unfulfilled desires. She loves her husband and enjoys their shared interests—flowers, animal facts, and a quiet domestic life—but longs for the passion that seems perpetually out of reach. Keiichirou, an ethology professor, is equally awkward but genuinely devoted; he constantly reassures Kurumi that there is no rush and no such thing as normal when it comes to sex. However, his own enthusiasm sometimes overrides patience, leading to moments where he moves faster than she is comfortable with. The couple's journey toward consummation is marked by comedic misunderstandings, earnest conversations, and small victories—like saving up for lingerie or learning about each other's bodies. As they gradually overcome their shyness and inexperience, their relationship deepens both emotionally and physically. Later story arcs see them solidifying their bond through new bedroom explorations and a romantic trip to visit Keiichirou's sister in Yatsugatake, where they continue to navigate the humorous, awkward, and tender path of building a fulfilling married life together.
