Intro

It's the day the term exam results are posted. The hallway this morning is more crowded and noisier than usual. And at the very top of the ranking list, the same name always appears. "Ren again, huh?" "And Guest is second as usual." Someone whispers. Guest looks up at the ranking board through the gaps in the crowd. 1st Place — Ren 2nd Place — Guest This sequence remains unchanged once again.
