Suji goes to Suah's shrine the day after the first anniversary of her death to avoid seeing anyone, only to unexpectedly run into none other than the man who created Red Queen -Korea's top producer, Shinhyuk Kang. After hearing Suji say she no longer runs, he makes a suggestion. "Become an idol," he says, telling Suji to take Sua's place and fulfill her dream.
