Yuki and her husband Kenshi have just started their newlywed life in a small apartment. Frequent visits from her kind-hearted father-in-law, Tohru, initially seem like genuine concern for the young couple. However, his seemingly gentle demeanor hides a dark, obsessive desire for Yuki.

From that moment on, he waits for her every day, using the same manipulative tactics to satisfy his uncontrollable lust. His actions are no longer mere attraction—they reveal a dangerous obsession fueled by relentless desire.
