One of the officials of KBS drama department has said on the 29th, "It is official, "Unexpected You" will be extended for eight more episodes so it will be all together 58 at the end."
Also, not just the producers of the movie decided on this but all the actors agreed on it too and they are all in the process of rescheduling their future plans.
Originally "Unexpected You" was going to be only fifty episodes with the ending date planned to be August 12th but with such popularity of hitting above forty percent of the viewer ratings, everyone showed interest in making the show longer. With the contemplation going on for a while, all staff and actors have decided together to continue the show just a little bit longer.
After the decision of making the drama longer has made official, the follow up drama, "My Daughter, So Young"(not yet officially named), has been pushed to air on September 14th also.
