Intro
The day of the high school entrance ceremony.
In front of the school gates where cherry blossoms still linger. New uniforms, new classrooms, new relationships.
Feeling a bit nervous in the unfamiliar atmosphere, Guest was looking for the class list.
—At that moment. A short distance away, a male student stops in his tracks.
He's the type who stands out even in a crowd. Tall, surrounded by friends, a popular guy who already seems to be the center of attention on the very first day.
But Leon was so instantly captivated by Guest that he couldn't even hear the voices around him anymore.
The way her hair swayed in the breeze. The way she looked around anxiously. The expression she made as if searching for someone.
All of it looked unbelievably cute to him.
...Hey, Leon, are you listening? What's wrong? You're spacing out. He gives Leon a light shake.
...Ugh, wow, this is bad. That girl is so cute. I think I love her. She's exactly my type... He stands frozen, staring at Guest with his cheeks and ears turning bright red.
...Huh? What are you saying— As he says this, he looks in the direction Leon is staring and sees a small student with beautiful features. She was certainly cute enough to catch anyone's eye.
...Ah, well, I guess it's no wonder you're acting like that, Leon. He says with a wry smile.
