Yu Seon Ho succeeded in arriving at his mission place first of all the cast members, thanks to a Greek student who guided Yu Seon Ho to his destination. The full mission was to take the exact same photo as the mission photo he was given once he found the site. Yu Seon Ho should've had no problem passing his mission since he arrived at his destination first, right?

Unfortunately, it turns out Yu Seon Ho is terrible at photography angles! The first two tries, Yu Seon Ho failed because he took selcas in front of the grave, even though no one was in the photo on the original mission card. He then failed again by taking a photo of the grave from a completely opposite angle to the original. 

Yu Seon Ho revealed that it took him almost 30 minutes to take the photo from the correct angle. Watch his struggles in the clips above and below.
