TVXQ was very popular nowadays. They influenced the country in many aspects. The members also lived in a beautiful life that everyone dreamed. They had money, power, and name.

          One day, a 7 years old boy came to their house and claimed as Junsu’s son. Soon after, their life became worse and complicated. Junsu had no choice except to live with the kid. But soon after they lived together, he wanted to be a good father for the kid. Remembering the past, he wouldn't repeat his biggest mistake for twice for sure. And he had chance just for one month.

          During the hard days, the TVXQ members learnt love, fighting, and sacrifice, especially for Junsu. He learnt love from the kid. He learnt fighting for the kid. He sacrificed everything for his precious. He used to be an obedient kid or seemed like a coward. He used to be an irresponsible man. Whether he realized it or not, although the kid gave him a rough life yet the kid also made him more mature.
