Her Perfect Prisoner is a 31-episode yuri short drama featuring two yandere leads. Powerful gang lord Cassandra tracks down Raven, the girl who saved her ten years prior, then kidnaps and locks her in a villa out of overwhelming guilt and obsessive possession. Cassandra imposes strict rules, surveillance and harsh restrictions to keep Raven all to herself. Yet Raven is no innocent victim—she planned their reunion for a decade, acting weak and timid on purpose to lure the obsessed Cassandra deeper into love. Their twisted cat-and-mouse game unfolds with jealousy, power struggles and hidden schemes. After layers of secrets and mutual suspicions, both finally realize they are equally addicted to each other, turning one-sided captivity into mutual obsession, ending as equal, complicit lovers bound together forever.
