Scramble Love — a mega-hit Japanese romantic comedy manga that has sold over 10 million copies. The protagonist gets possessed into that manga, which they have never once read, as a background extra with zero importance named Kim Yoo-sung. But it turns out this guy is a genuine hardcore otaku who even does cosplay. To live a comfortable life without raising suspicion, the protagonist decides to study every kind of romcom trope out there and play the part of an otaku extra convincingly. But then — why do heroine clichés keep triggering whenever they’re around? And not just with one heroine, but multiple?! “This is getting seriously out of hand…!?”
