One day in late fall of the second year of high school. A yellow-haired transfer student, Ju Eun-seom, appears at a peaceful high school with strange rumors. Contrary to the gruesome rumors, he has a dazzling appearance and students begin to admire him. At her younger sister's request, Cheon Yi-seo secretly leaves a gift at Ju Eun-seom's seat. The following year, the two of them run into each other in the same class. Ju Eun-seom, who greets Cheon Yi-seo normally, for some reason shows a particularly prickly wariness... "Ha... Keep it down, really. If you show it, I'll kill you."
