Shy and unassuming, Sarang is your run-of-the-mill office worker. Never the assertive type, she's spent her entire life trying to please others and making their lives easier. She is just a background character in other people's lives. That is until after a traffic accident she wakes up as the main villainess in her favorite mobile romance game. Determined to avoid her character's tragic fate, Sarang now must break out of her defined role and change the outcome of the game.
