Starting with the shocking premise of a will discovered at a grandfather's funeral, where sister couples inherit a massive fortune, this work immediately draws you in with its dramatic twist that tests marital love and trust. The theme of spouse swapping among close relationships, unlike swapping between strangers, carries an overwhelming sense of immorality and prompts deep reflection on the future of interpersonal dynamics. Particularly, the fact that not both couples move in the same way from the start, but act with near-revengeful emotions, adds realism and depth to the narrative.

The performances of the actresses shine in this piece, with Okui Kaede's nighttime scenes being especially arousing and passionately acted. Other actresses also fully display their sensuality with voluptuous bodies, making it highly practical in that regard. The intimate scenes are carefully constructed, with a perfect balance between drama and eroticism, elevating it beyond mere adult entertainment.

I was once again impressed by h.m.p's production skills. The casting is excellent, and the drama crafting is so adept that it completely immerses you in the story world. While it's possible to watch ignoring the plot, enjoying the well-structured drama provides a deeper sense of satisfaction. The story ends harmoniously, yet it leaves you curious about an opposite outcome, creating a lingering aftertaste. I earnestly hope for a series continuation—it's a masterpiece that fans of this genre will find irresistible.
