KasuRich

University student Mikado Kasuga lives for his favorite streamer, Zurich (real name: Rihito Nakahara). Convinced he's the only one who truly understands the man behind the screen, Mikado goes to an event to see his idol in person. But their meeting doesn't go the way he imagined—and Mikado soon learns that Zurich also has a peculiar and mutual attachment to him. A unique BL about the twisted, codependent bond between an obsessive streamer and possessive fan.
