Former Jewelry member Seo In Young is currently in the last stages of preparation for her comeback this December. This will be her second cycle promoting as a solo artist since withdrawing from Jewelry last year. Her solo debut kicked off with great success with the release of her digital single, "Love is Bitter, Pain is Calling", back in June 2010. Psy will be featuring in Seo In Young's next title track, which was reportedly his thank-you gift to the singer after she guested in one of his tracks, 'Thank You', for his 5th album 'PSYFIVE'. Many of her fans are anticipating her comeback track, as it was recently hinted that it will be a strong song in the dance genre. Source: Daily Economy
