S1E407 — Switzerland and the UK Part Two

The trip continues! Haha and Se Chan spend the night at a stargazing hotel where they can greet the grand mountains upon waking up. Ji Hyo, Han Na, and Jong Kook get to paraglide on the Alps and make memories that they will never be able to forget. Meanwhile in the UK, Kwang Soo and Sang Yeob turn off the lights and get ready to go to bed. Suddenly, they see a red light. What could it be?
