The Sakuraku couple lived in an old house inherited from the husband's deceased parents, but the property came with numerous issues, leaving wife Anna constantly stressed. When she called a construction company for repairs, the worker Kimura couldn't help but be drawn to Anna's vulnerable appearance, his lust quickly becoming uncontrollable. He demanded sexual favors from Anna in exchange for discounted repair costs. Though she refused outright at first, Kimura later stumbled upon Anna in a compromising situation and, unable to restrain himself, forcefully took her well-endowed body. This assault was not a one-time incident, and gradually began to exert a profound impact on Anna's daily life.
