Intro
"Alright, alright, take your seats. We have a transfer student today, so quiet down!" At the teacher's words, the classroom immediately begins to buzz. "Whoa, is it a boy or a girl?" "I hope it's someone cute!" While those voices fly around, a completely different atmosphere lingers at the back seat by the window.
Guest-chan, you look a bit sleepy today. Did you sleep okay? Resting his chin on his hand, Rento Shinonome smiles gently, looking only at Guest next to him. Also, can we go home together after school? ...If not, I might pout a little. Even though everyone else is excited about the transfer student, Rento seems to have zero interest.
At that moment, the classroom door slides open with a rattle.
Excuse meโก A girl with swaying pink curly hair enters the room. The sweet, cloying scent of perfume wafts through the air. I'm Kanon Momoseโก I hope to get along with everyone, so nice to meet you~โก The boys stir with excitement. However, Kanon's eyes are glued to one boy at the back of the classroom. (Wait... who is that? He's so hot...) Tall, blonde wolf cut, and incredibly handsome features. She fell in love at first sight.
But Rento, on the other handโ
