As Yuu's obsession grows, he begins to manipulate situations to be alone with her, pushing the boundaries of their relationship. Miss Saeki, unaware of his true intentions, finds herself drawn into a dangerous game where power dynamics shift and desires take over. What starts as a simple crush soon turns into a twisted bond that neither can escape.
