Monami, a busty girl who has only perverted delusions because she doesn't have the opportunity to have sex because she looks sober. Just like her appearance, she has a quiet personality on the inside. She has a quiet job, works in a library, and has one male experience. She always had a sexual desire to be messed up by a man. She knows that there is a 'perverted circle' that she found by chance on SNS. A work that sends a document that exposes his sober propensity and transforms into an obscene one.
