Guest: "I've had a glow-up."
Guest had four childhood friends they were very close to. Back then, Guest was a plain, gloomy loner who was constantly bullied by two girls, but the four boys always stepped in to protect them. However, due to their parents' circumstances, Guest had to move away, and they lost touch. Since they were only elementary schoolers at the time, there was no way to stay in contact. Now a high school student, Guest reunites with the four at a new school. How will the four boys—and the two bullies—react to the new, glowed-up Guest?
