It's been a year since we got married...My wife, Hitomi, is living a happy life with her beloved husband. After seeing her husband off to work, she was cleaning the garden when a man suddenly appeared in front of her. ``Sister-in-law, it's been a while. You're still a good girl~'' The man was Takeshi, her husband's younger brother... Hitomi's younger brother-in-law. ``I barely know Takeshi-kun, but my husband hates him.'' I can't express it in words, but I can sense something ominous in his eyes. Those bad premonitions become reality one after another...
