Hae-na has a crush on one of the male teachers at her school. After a few drinks at a get-together with the teachers, she discloses her feelings to him. However, after she kisses him, she realizes it's Seo-won, the man she can never get close to.

A new student, Ji-a, transfers to Garam High School, and she turns out to be a shaman. She notices a different energy around Hae-na and Bo-gyeom. Hae-na fails to kiss Seo-won, so she has to seek her chance during the school trip. Meanwhile, some of the students sneak out at night, so Hae-na ends up going outside to look for them, risking herself to be exposed.
