Description: Ha Ni and her younger brother, Sandeul, suffer from the rare MCS tumor syndrome, a condition that causes children to transform into "monsters" when it strikes. To avoid strange looks, they must disguise themselves, hide, and perpetually "act normal." Just as they transfer to a remote school, attempting a fresh start, they encounter a classmate named Yeon-woo, who refuses to take medication or hide his illness. He suffers a sudden attack in public, transforming into a hairy monster, becoming the object of fear and ostracism. Due to misunderstandings and myths surrounding the illness, it is gradually exaggerated, sparking public outrage and leading to his public hunting by villagers. --In this world, "normal people" are sometimes more cruel than monsters.
