Both Night Traveler and Whale Star: The Gyeongseong Mermaid tell stories about love that is difficult or impossible because of external circumstances. In Night Traveler, the barrier is time travel, while in Whale Star, it is the harsh reality of historical conflict during the Japanese colonial era.

Both focus on emotional, slow-burn romances where characters must make sacrifices, often choosing between love and something greater, such as duty or survival. They also emphasize quiet, introspective characters and explore deeper themes beyond romance, including identity, history, and personal struggle.

Overall, the two stories are similar because they portray tragic, meaningful love shaped by forces beyond the characters’ control.
