It is the last day of the trip for Hae In and his friends. They are at the Niagara Falls to enjoy the magnificent experience that Mother Nature has prepared for them by all means possible. A zipline will provide them with a view from above, a cruise tour will present them to a whole new level of excitement, and lastly, they will go for a walk toward the waterfalls. In the end, at their last meal together, Hae In and his friends share their honest and innermost feelings.
