Amai Ijiwaru

Following her parents’ divorce, Kotori lives alone with her father, Naoto. Over time, her innocent affection gradually transforms into an intense longing as Kotori desires to replace her mother’s position in her father’s heart. Meanwhile, Naoto tries to suppress his instincts, turning to paid “Papa-katsu” dating services as a secret outlet to relieve his physical urges.

Everything spirals out of control when Rina—Kotori’s timid, quiet best friend—reveals a dark, calculating side. She suddenly approaches Naoto in a semi-nude state, exposing her body while holding up her phone displaying recorded footage from her own secret paid dates.

Rina swiftly issues a calculated threat: she will keep Naoto’s double life a secret from Kotori, provided that he submits to and satisfies every single one of her physical desires. Cornered by subtle blackmail and raw temptation, Naoto finds no way out and falls completely into the sweet yet dangerous trap set by his daughter’s best friend.
