The date that day was supposed to be perfect.

At the oyster specialty restaurant they had booked long ago, they enjoyed fresh seafood to their heart's content. Even after returning to the apartment they shared, a peaceful and happy atmosphere flowed between them. Until the moment they climbed into bed together, turned off the lights, and closed their eyes, there wasn't a single sign of anything threatening their daily life.

However, in the silence of the night, a strange chill suddenly attacked Renya's body.

It was a clear emergency. Renya's body began to tremble violently on the sheets, and his face, drained of blood, turned deathly white in an instant. Cold sweat seeped from his forehead, and unable to bear the intense discomfort, he instinctively pressed his hand firmly over his mouth. The next moment, an ominous sound—gurgle, splosh—echoed from deep within his stomach in the quiet bedroom. In addition to the fierce, stabbing pain in his lower abdomen, a tremendous surge of nausea welled up from deep in his chest. Besieged by pain from both above and below, Renya could no longer even move.
