Eun-Yeong Baek

A first-year high school student who lives in the supposedly-haunted old dorm house. He's constantly butting heads with Hae-Jun, his new dormmate, due to his selfish behaviour and messy nature. He's always surrounded by friends, to whom he seems bright and fun, but to Hae-Jun he's cold and snarky.

Although the two get on each others' nerves, they realise that they both have nowhere else to go, and must live together in the run-down old dorm.
