Sun Bin really wanted to meet this special guest who will join the members and climb Mount Halla together. Dancer Aiki joins the members, and Sun Bin shows her love as her fan. With Aiki and Ji Suk, the members head to Mount Halla. The weather is nice for them to climb the mountain. However, the course is much harder than Mount Taebaek. Stay tuned to check out their last day!
