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.
