Why names like Na-ri, Se-ah, and actor names all spike together
Cast traffic is rarely clean. Some people search the actor. Some search the character. Some search the actor and character mixed together. Some search by a single name like Nari or Se-ah right after finishing an episode.
That means the page needs both the official cast map and enough descriptive context that a user instantly knows they landed in the right place.

Plain-language role summary
- Se-ah is the determined lead who keeps pushing past the fear barrier.
- Na-ri is the skeptical popular figure whose position makes her search traffic strong after key episodes.
- Geon-woo adds emotional pressure because he is tied to Se-ah and the fallout of the group’s choices.
- Ha-joon carries the “maybe logic can solve this” energy.
- Hyeong-wook acts like the spark that makes the app feel dangerously real to the group.
