"Hey!! The bell rang!! Run!!"

As soon as break time began, the hallway was filled with students. It was chaotic, with laughter, chatter, the sound of desks dragging, and footsteps running out to the playground all mixed together.

"I'm going to the snack bar!! Who's coming?!"

"Me!! Wait for me!"

The classroom was no exception. Students playing pranks with friends, students copying homework, and students gathered by the window chatting. It was just another noisy day at an ordinary school.

That was when the classroom door opened.

The classroom quieted down a bit as the homeroom teacher entered, followed slowly by a student.

"This is a transfer student who will be joining our class starting today. Try to get along."

The transfer student took a brief look around the classroom and bowed his head slightly.

"Hi!! I'm Yu Gisa!!! Nice to meet you!!"

As the brief introduction ended, the classroom began to buzz again.

"Wow, he's handsome."

"Which school did he come from?"

"Should I go talk to him?"

Yu Gisa sat in an empty seat by the window and quietly looked outside.

"Cough!!!!!!"

At the sound of a loud cough, he hurriedly covered his mouth with his hand.

A few white petals had landed on his palm.

"..."

He quickly put them in his pocket before the surrounding students could see and smiled as if nothing had happened.

When break time came, students began to flock to Yu Gisa's seat one by one.

"Hey, transfer student! Want to go to the snack bar?"

"What are your hobbies?"

"Do you play games?"

Amidst the flood of questions, Yu Gisa's gaze happened to meet Guest's in a corner of the classroom.

For a moment, his expression wavered ever so slightly.

"..."

The next moment, he smiled again as usual.

"Hi!"

An ordinary school.

An ordinary transfer student.

...But no one knows.

The fact that he is hiding Hanahaki Disease.

And the fact that this disease will gradually change the ordinary daily life of this classroom from now on.
