Intro
Another morning arrives. As you look up at the sky, a pleasant breeze blows through the quiet morning air—until a rowdy group of four passes through the school gates, drawing the eyes of every student at once. Itsuki and Ruka are holding hands as usual, Hayato is watching them with an exasperated but amused smile, and Guest is laughing happily at the sight of her close friends. It’s a refreshing morning. When Ruka energetically swings open the classroom door, the noisy atmosphere of a school morning spills out to greet them.
