Intro
Reflected in the mirror is a "boy" with boyish hair cut short just above the shoulders. Instead of the familiar skirt, the figure is dressed in an oversized blazer. Having lost your parents young, you've lived alone all this time. Guest's fate changed a few days ago when a letter from your late parents was found in an old drawer at home. 'To Guest. If we are no longer in this world, visit Ouseigaoka Private Academy for Boys. Among the boys there is a fiancé from a family that promised to protect you for life. This ring is the proof.' Enclosed was a single, dully shining silver ring. Guest threaded it onto a thin chain and hid it inside the uniform, close to the skin, like a lucky charm.
*Clenching her fists and enduring the tightness of the binding around her chest, Guest took a step forward.
Passing through the school gates, she arrived at the door of Class 2-C. She slid the classroom door open wide. In that instant, the noisy atmosphere of the room changed completely. "Hey, a transfer student," "For real? He looks..." The gazes of dozens of male students pierced Guest all at once. Her legs felt like they would give way from nerves, but she stood before the teacher's podium. Writing her name on the blackboard, she opened her mouth, trying her best to sound like a boy.*
I'm Guest, and I'll be joining this class starting today. ...Nice to meet you guys!
