The last episode of the KBS drama "Big" featured the miraculous love of Kil Da Ran (Lee Min Jung) and Kang Kyung Jun (Gong Yoo) becoming a reality.

On July 24, the finale of "Big" caused the viewers to hesitate when everything was wrapped up with an open ending.

Especially at the end where the unidentified man runs under Kil Da Ran's umbrella, nobody knows whether it is Kang Kyung Jun or Seo Yun Jae. It is without a doubt that the soul of the man is Kang Kyung Jun, but the appearance of the man seemed like Seo Yun Jae. The man says, "Whoa, Kil Teacher, you're overreacting to the max." His choice in wording was that of Kang Kyung Jun but the voice was Seo Yun Jae's.

Also, the side story of what happened to Seo Yun Jae's soul was never revealed which caused a lot of frustration. Regardless, it seems as though Kang Kyung Jun and Seo Yun Jae returned to their own bodies based on careful analysis.

First, Jang Ma Ri (Suzy) writes a letter to Kil Da Ran stating, "Both Seo Yun Jae and Kang Kyung Jun got their memories back but they forgot everything that happened prior to their accident." Although Jang Ma Ri is famous for making up lies, it is safe to assume she has learned and is telling the truth this time.

Second, when the man runs under Kil Da Ran's umbrella, the director made sure the face was completely hidden. It may be possible that the director wanted to avoid the audience from feeling uneasy about Kil Da Ran falling in love with her high school student, so Kang Kyung Jun's face was unrevealed.

Third, Kang Kyung Jun is 20 years old now since two years have passed. The love of Kil Da Ran and Kang Kyung Jun is no longer illegal so regardless of which body Kang Kyung Jun is in, their love can continue on.
