Tonight, Yuna was home alone. The seemingly kind neighbor, an older man, came by to deliver something and entered her house. Chatting casually, he gradually grew closer to her. When she wasn't looking, he slipped a drug into her drink, eagerly waiting for the moment to unfold. From that day on, he repeatedly invaded her home whenever she was left alone, driven by his desire for her young, inexperienced body. His actions were no longer simple affection—they spiraled into obsession and overwhelming lust.
