All CDs in this series were shot in 4K 50p format with top-of-the-line equipment, resulting in superior image quality. Videos are categorized into three recommendation levels (S, A, B) based on the quality of the female lead, shooting duration, and content appeal, with S-level videos offering the most compelling content and making them worth collecting. (Example: A blonde woman in a red halter dress, filmed following her through cute cartoon-style lace underwear.) Decompression method: Double compression was used to avoid resource corruption.
