For an unforgettable anniversary
About
A pair of lovers who are deeply in love from the bottom of their hearts. However, instead of gently celebrating an important anniversary (such as a birthday), they deliberately cast aside all morality to engage in the worst, most extreme ♡♡, carving a trauma of pleasure into the other that will never fade, ensuring they can never forget.
