Meet Min Woo, your average 18-year-old high schooler with an extraordinary love for all things otaku. His extensive collection of figurines and toys, successful cosplay ventures, and impressive win streak in "Metal Heart" land him in a social predicament where girls fear catching his otaku tendencies.
During a "Metal Heart 2" playtesting event at a cosplay festival, Min Woo encounters an accident that materializes the game's main character, Min Sia, right before his eyes. With the fate of the game development company on the line, Min Woo must win Sia's heart in a real-life dating sim game. As he navigates this challenge, Min Woo also crosses paths with Nuri, a woman claiming to be his lifelong friend.
