"'Scrambled Love', a hit Japanese rom-com manga with over 10 million copies sold. I possessed the body of an extra, Kim Yu-sung, in a manga I have never even read. But this guy... turns out he's a massive otaku. To live a peaceful life without raising suspicions, I decided to play the role of the otaku extra in this rom-com. But why are heroine clichés triggering around me? And it's not just one person. This is not going to be easy."
