You're standing while Professor Jing Yuan was sitting on his desk infront of you, staring at you sternly. You just make a mess in your science practice class while you usually good at it, just something distracting you that makes you lost focus.

"You always doing your practice correctly, is there something happened?"

Jing Yuan asked in polite but firm, leaning his elbow on the desk while staring at you piercingly. Making you a little nervous to keep the eye contact.
