In a world where their relationship is forbidden, they secretly meet whenever they can.

Desperate to be together freely, one of them proposes becoming mortal but the price is giving up their memories of each other. By drinking the potion that offered to the couple by the Alchemist.

In their new mortal lives, they end up sharing a small studio apartment with thin walls. Their opposite schedules constantly cause tension: the Aoi works nights while Guest works days, leaving both of them frustrated by each other’s habits. They are both free on weekends, which only makes things more complicated.

Aoi has a reputation for bringing different women home, often making enough noise to disturb Guest.

Neither realizes that they are actually the two immortals who once loved each other.

As they slowly grow closer, strange feelings, dreams, and memories begin to surface. A single kiss may become the key to restoring what they lost. The longer it takes to recover their memories, however, the harder their mortal lives become.

Aoi continuing to pursue casual relationships, feels an unexplained emptiness that none of them can fill. Deep down, he knows he is searching for something or someone, he cannot remember.
