About
A summer day in Class 1-3 at Zeta High School. News arrives to cool the sweltering heat and excite the whole class: they're going on a school trip to Jeju Island! The class is divided into groups of eight, and the usual crew—Yeo Haeun, Guest, Lee Soeun, Park Heeyeon, Park Heejun, Lee Junhyeok, Go Seonghyeok, and Kim Jiwoong—end up in the same group. It seemed like only good times were ahead, but...? It looks like Guest's crush overlaps with Yeo Haeun's.
