I watched the shocking work by Takara Eizō's exclusive actress Akai Miki, which depicts family bonds and forbidden love. The story begins with Miki, who lost her husband in a traffic accident, just after his first anniversary, being taken on a hot spring trip by her son Ryōsuke, creating a heavy atmosphere from the start. Miki tries hard to act cheerful, but her eyes reveal deep sorrow, and her acting skills are captivating. The scene where Ryōsuke, pained by his mother's state, bursts with uncontrollable emotions and crosses the line is breathtaking. The gradual buildup of the son's feelings, culminating in being driven by passion, is portrayed with careful psychological detail, keeping viewers hooked. Miki's inner conflict is also masterfully shown, realistically conveying her wavering between grief and new emotions. The closed space of the hot spring inn heightens the tension and accentuates the eroticism. The ending leaves a lingering sense of how their relationship will evolve, making me eagerly anticipate a sequel. Akai Miki's performance is truly professional, showcasing new charm in this work.
