In a bustling apartment filled with tension and anticipation, a dramatic game of seduction and competition unfolds. The story begins with 若 (Waka), a man who suddenly finds himself in a situation he never expected. He's confronted by 和歌 (Waka), who reveals that he has been diagnosed with a rare illness, one that could leave him bedridden. But even with this revelation, he's determined to stay with her, no matter the cost.
The game begins as a challenge, a test of endurance, passion, and willpower. Waka is invited by アリタ (Arita), a woman from a company that organizes a special game event. The prize? A staggering 1 billion yen — enough to cover his treatment. But to win, he must face off against a series of intense and intimate challenges, each more demanding than the last.
Among the participants are 赤ちゃん (Akachan), a young woman who has a complicated past with Waka, and 姉ちゃん (Anechan), her older sister, who has a fierce and playful rivalry with Waka. Other players include マサちゃん (Masa-chan) and マンゴーちゃん (Mango-chan), each bringing their own energy and flair to the competition. The game takes place in a variety of settings — from a small, intimate room to a larger, more dramatic stage — and each round brings new challenges and surprises.
As the game progresses, Waka faces not only physical and emotional strain but also the rekindling of old feelings and new rivalries. With every round, the stakes rise, and the participants are pushed to their limits. The tension builds as the game reaches its final stages, with Waka facing off against his former lover and the woman who once caused him heartbreak.
In the end, it's not just about winning the 1 billion yen prize — it's about proving his strength, his love, and his will to fight for what he truly wants. As the game reaches its climax, the outcome is uncertain, but one thing is clear: Waka has come a long way, and the journey has only just begun.
