Dokuzetsu no S na Ore ga Jimi Riman ni Kuwaresou desu

A sharp-tongued and sadistic young man finds himself drawn to a plain, unassuming office worker he meets at a video store. Their initial encounters are marked by his teasing and provocative remarks, but the seemingly ordinary man does not react as expected. Instead, a strange and intense dynamic begins to develop between them, blurring the lines between dominance and submission. As their interactions grow more frequent, the sadist discovers that his usual tactics may not work on this quiet individual, leading to an unexpected shift in their relationship.
