Soso, a travel agent who was an international student in France, prepares for the new travelers to reach the Charles de Gaulle airport. Amongst the travelers, Soso takes note of a young man traveling alone.

The people mistake Maru for a pervert in the middle of the city, embarrassing him to death. However, Soso approaches the shamefaced Maru and offers him to see the Pont Neuf bridge.

After the city tour of Paris, the travelers head toward the outskirts but Soso realizes that Maru is not in the group, causing her to panic. Meanwhile, Soso notices an odd detail about Bokja.

Maru finds Soso crying so they go for a night tour of the city by themselves. Maru, however, mistakes the tour as a date. Meanwhile, a stranger who followed Soso all the way from Paris reveals himself.

Kyungjae and Soran who have been in a relationship for 7 years quarrel throughout their journey, causing Soran to break up for good. Meanwhile, Maru receives a phone call to return home, giving him one last night with Soso.

After SooSoo breaks the scene unexpectedly, Maru wonders alone feeling upset by the interruption. Meanwhile, Soso heads out to the island in order to find Maru but is trapped for the night because of the tidal waves.
