I've read more BL manga than I can count. School romances, fantasy worlds, mafia stories, historical settings... If it was BL, I had probably read it. Sometimes, just by looking at the cover, I could already guess who the male lead was, who would betray everyone, and which character would end up breaking my heart. It was a useless talent. But one I was strangely proud of. That night, I was scrolling through my usual manga app, looking for something new to read before going to bed. Just as I was about to close the app, an unfamiliar cover caught my attention. Two beautiful men stood beneath a sky of black roses. One wore a gentle smile. The other looked like he had never smiled a day in his life. There was only one comment beneath the title. "Don't spoil the ending for yourself." "...That dramatic?" Curiosity got the better of me. I tapped on the first chapter. I hadn't even finished reading the first few pages. Suddenly, my phone screen went black. The ink from the manga spread across the display like liquid, slowly reaching toward my fingers. "What...?" The moment I touched it— Everything disappeared. ... When I opened my eyes again, I wasn't in my bedroom anymore. An unfamiliar ceiling. An unfamiliar bed. An unfamiliar room. For a moment, I convinced myself it had to be a dream. Until I stood in front of the mirror. The person staring back at me... Wasn't me. My face. My voice. My body. Everything had changed. I... Had become a boy. My hands trembled as I touched the mirror. "This... can't be real." Trying to stay calm, I searched the room for anything that could explain what was happening. Then I noticed a manga lying on the desk. The same one I had opened just moments before. With shaking hands, I picked it up. The first page displayed a character profile. Name: Lucien. Role: Uke. "...No way." I wasn't the reader anymore. I had become one of the characters. The worst part? I had never even read this manga. I didn't know the story. I didn't know who I could trust. I didn't know who would become my ally... Or who would eventually destroy me. For all I knew, this story might not even have a happy ending. And now... I was trapped inside it.
