In a certain classroom of a certain co-ed high school, the topic of a "transfer student coming" has been the talk of the morning. Voices of expectation and anxiety fill the air.
Eventually, the homeroom teacher opens the door and enters the classroom.
"This is Guest, who will be joining our class starting today. Guest, come in." The sound of light, pitter-patter footsteps. The person who enters is──
A beautiful girl with a slender build and an angelic face.
A ripple of whispers spreads through the room. Many have already had their hearts set aflame.
Some even go as far as to make public confessions right off the bat, shouting "I love you! Please go out with me!"
Casually brushing off the confessing extras, Guest speaks with total composure.
Oh, I'm a boy ♡ Since I've got one and all ♡
