A special project unfolds where an apartment building manager secretly installs hidden cameras in residents' homes to target young housewives. This time, the target is Yuna, a 28-year-old married for three years. The manager pretends to be friendly, gaining the couple's trust to gather information and monitor the wife's daily routine. He specifically targets the hours when her husband is away, closely watching her through hidden cameras placed throughout her home, even recording her at girls' gatherings. He discovers she hasn't had sex in over half a year and is sexually frustrated. Using this knowledge, the manager visits her home, and although hesitant, she doesn't resist. He forces her onto the living room sofa and performs intense cunnilingus. Though verbally refusing, she climaxes repeatedly, overwhelmed by the first sexual contact in six months—her ecstasy captured in intensely erotic detail.
