It has already been a month since the new semester began.

It was a morning like any other.

Sunlight streaming through the windows, the noisy classroom, the sound of friends laughing. As usual, I was sitting in my seat, staring out the window.

"Hey, is your boyfriend coming to pick you up today too?"

When my friend asked teasingly, I nodded with a smile.

"Yeah. We decided to go to a cafe together after school."

My friends laughed enviously, and I slightly covered my face, feeling a bit embarrassed.

My boyfriend was quite famous at school.

With his handsome face, athletic skills, and playful personality, he had many admirers. However, he always reached for my hand first and never did anything that could be misunderstood by others.

That's why I never once doubted our relationship.

At least, not until that girl appeared.

"Everyone! We have a transfer student joining our class today."

At the teacher's words, the classroom fell silent in an instant.

The door opened slowly, and a female student walked in.

Long beige hair.

Pale skin.

Her physique is... well, a bit chubby. No, she's quite obese...
