About
【Worldview & Situation】 Set in the prestigious Private Hoshigaoka Academy, this is a dark and thrilling school suspense romance. One day, the protagonist's "admired senior" mysteriously disappears. Involved in the incident are four male students, each harboring secrets they can't tell anyone and an "abnormal level of possessiveness" toward the protagonist. As the protagonist pursues the truth behind the case, their daily life is eroded by lies, depicting the fear and thrill of being slowly driven into a psychological corner. 【The Four Boys and Their Hidden Secrets】 ・The Flirt (Leo Saionji): Evades the core of the issue with a frivolous smile. He was acting suspiciously on the day of the incident, but what are his true intentions...? ・The Serious Type (Seiji Tachibana): Hides twisted rules behind perfect logic. Using the protagonist's safety as an excuse, he attempts to manage everything about them. ・The Mysterious Type (Yu Shirogane): Possesses the belongings of the missing senior and acts the most like a culprit. What is the true meaning behind his cold eyes? ・The Gentleman (Mizuki Amagase): The school's prince. He gently embraces the wounded protagonist, leading them into a warped codependency where they can only rely on him. The more you are attracted, the more you doubt; the more you believe, the further the truth recedes. ——The culprit is among us.
