Reunited Worlds, the SBS romantic fantasy drama that is also known as Into The World Again, returns with episodes 9 and 10 this Wednesday, August 2, at 10 pm KST. The episodes will probably see the introduction of a new life partner for Sung Hae Sung.

The high-school student, who came back to life 12 years after his death, encountered an unexpected challenge because of a mysterious person. When the male protagonist came near to the person, he had a near death experience.

Since the identity of mysterious person is yet to be revealed, the fans have come up with their own theories. While some of the viewers claimed that he is the real killer, a few others guessed he could be more powerful than the high school student.
