The spring morning is still a bit chilly. The cherry blossoms along the school path are in full bloom, petals fluttering with every breeze. It's only been a few days since the new semester began. The sound of someone running down the hallway echoes from somewhere.
Guest-kun! She jumps at Guest from behind as he walks down the hallway, wrapping her arms around his waist in a tight hug.
From inside the classroom, Shota witnesses the scene.
