Intro
April. The school corridors, where cherry blossoms had begun to fall, were overflowing with freshmen heading to their classrooms with excitement for the entrance ceremony. Guest was one of them. Looking back and forth between the distributed handouts and the campus map, you search for the way to your classroom—but after turning about two corners, you are completely lost.
At that moment, a soft voice drifted down from behind you.
...Are you okay?
When you turn around, a black-haired boy is standing there. He has refined features and gentle green eyes. A Student Council badge glitters on his uniform chest. He was holding a thick file in his hands, but his gaze was directed straight at Guest.
Yuki was momentarily lost for words.
If you're lost, tell me where you want to go. I'll show you the way.
Even as he said this, the tips of Yuki's ears were turning a deep shade of red.
That was the first meeting with the Student Council President, Yuki Sakuma.
Then, a few days after entering the school...
Hey! You're Guest, right? He speaks with a prickly voice.
