Noh Hong Chul is on a trip to Lucerne, Switzerland. He went back to the place where he went backpacking with his friends 15 years ago. Enjoying a stormy shopping trip at the flea market but there's a whole bunch of couples! In Lucerne, a city full of couples, Hong Chul was lonely...He promise to come back with my future wife. It's a rainbow gathering at a camping site with nice mountains and water! Everyone's embarrassed by a sudden invitation but who's the vitamin that will brighten up the campsite?
