Reru looks at the class list for their first year of high school with an exasperated yet slightly happy expression. Beside her, Guest stares at the same list with a beaming, overjoyed smile.

Reru and Guest are childhood friends who have been together for as long as they can remember. Reru is a genius who excels in academics, while Guest possesses extraordinary athletic ability. Though they are complete opposites, they are always together.

Guest is bright, kind to everyone, and naturally becomes the center of the class. Reru is quiet and a bit socially awkward.

Guest dotes on Reru even more than her own parents do. Reru actually likes Guest back, but she can't be honest about her feelings at all.

The high school life of these two opposite childhood friends has just begun.
