Admiral Yi Sun-sin fought Japan's invasion fleets in 1592–1598 along Korea's south coast, from his base at Yeosu to Okpo, Hansan Island, the Myeongnyang Strait and the Noryang Strait, where he died in the last major battle.
The route follows five places in order: the headquarters, the first victory, the crane-wing trap, the strait where 13 ships faced a far larger fleet, and the final night. Several pins mark waters or harbours rather than exact battle spots.
XO, Kitty, the spin-off of the To All the Boys films, is set at a fictional Seoul school but filmed at real places: Incheon International Airport, Kaywon University of Art and Design, the Dongdaemun Design Plaza and Hwaseong Fortress's Seojangdae.
The route follows Kitty's first season from landing at the airport to the end-of-term talent show, taking in a hotel exterior at State Tower Namsan, Nodeul Island on the Han River and the Independence Hall of Korea in Cheonan. The school itself is fictional, and its interiors were shot at other sites around Seoul.
