Bored with the cold, stagnant peace of her married life, Haruka secretly signed up for a trendy "fetish matching app." Her goal was simple: to satisfy the twisted desires and calculated thrills that everyday life could never fulfill. Night after night, sneaking past her husband's watchful eyes, she met young men whose ideal conditions matched hers. It was supposed to be a purely dry relationship, fulfilling each other's fetishes. But one night, the sweet words whispered by a man in bed awakened a forgotten flutter in her heart. The boundary she had drawn for this game began to blur, and she willingly drowned herself in the bottomless swamp of depravity.
