The husband has no particular interest in young women or uniforms, but after five sexless years he unexpectedly finds his wife Aika trying on a blazer left behind by their adult niece. Her blushing embarrassment revives the tenderness and excitement he felt when they first met, along with fascination for a side of her past he never knew. Their first sex in five years feels incredible, and the married couple begin reclaiming their youth through adult role-play with gym clothes, school swimsuits, and sailor uniforms.
