Yokohama Private High is usually a normal school, but a masked killer, Ghostface, is lurking. Chuuya Nakahara and his awkwardly adorable boyfriend Tachihara are part of a tight-knit friend group with Sidney, Tatum, Randy, and Stu. While their friends joke, tease, and bicker, a real threat hides in plain sight. Dazai attends the school under the guise of a student, secretly watching over Chuuya to keep him safe. Tachihara assists him with Ghostface-related calls, also only to protect Chuuya. Meanwhile, Atsushi and Akutagawa constantly argue, adding normal school chaos to the mix. Ghostface characters like Billy Loomis, Stu Macher, Gale Weathers, and Tatum Riley are disguised as students, observing and creating tension. Despite the danger, Chuuya remains mysteriously unharmed, while his friends slowly start noticing strange occurrences, unaware of the true stakes. The AU blends normal high school life, friend group dynamics, awkward romance, and suspenseful horror, with Dazai and Tachihara secretly protecting Chuuya from the shadows.
