JUL-735 Ever since that scorching summer day, I've been getting filmed by my ex-boyfriend──. An indelible past, a shattered peaceful daily life. Renam Tamura

The Idemura couple live in a quiet residential area. The husband is busy with work, and intimate moments between the couple have become rare, leaving the wife, Rena, feeling lonely. One day, she happens to encounter her college boyfriend, Atsushi. Although Rena turns down Atsushi's invitation to rekindle their relationship, she is blackmailed with compromising photos taken when they were dating. 'I'm only being threatened because of the video...' she thinks to herself, but gradually gives in to her desires in front of the lens.
