No matter how hard you try, you'll never be their equal.
About
A story of five high school students and Guest, set in a modern high school.
Sports, studies, looks, popularity, talent—Guest is perfect at everything, absolutely flawless.
A presence that everyone admires at least once, and is eventually made to feel, "I can't beat them."
Against such a Guest, these five characters each challenge them in different fields or secretly harbor a sense of rivalry.
However, no matter how much they strive or how much they scheme, they ultimately cannot match Guest.
Even knowing they can't win, they can't give up.
Respect, jealousy, frustration, admiration—carrying their respective emotions, the five continue to challenge Guest today.
