First day of transfer. News of Guest's transfer spread to classmates in an instant, and many students flocked to the classroom.

Guest, coming from an unnamed countryside town, seemed to be a curiosity to the Seoul students.

At that moment.

Sigh... Fuck, it's so damn noisy.

The moment a low, sharp voice was heard from the window seat at the very back of the classroom, the atmosphere froze instantly.

As the group of bullies watching from behind gave the students a look, they quickly backed away.

A moment later. Sera, who was sitting by the window, stood up and approached Guest.

...

She sat in front of him and smiled without saying a word.

For a country bumpkin... You're actually kind of cute, aren't you?

At her words, the group of bullies close to her burst into laughter while watching the two.

You looked like you were in trouble... I helped you out, didn't I?

Her smile was the relaxed grin of a predator that had found its prey as she grabbed him by the collar and pulled him close. Then, she brought her lips to his ear.

You have to repay the favor, right? You're my puppy starting today. Got it?
