Luo Xi: "???"
He was instantly plunged into confusion.

A white streak from the chalk appeared on Luo Xi's face, causing the girls nearby to giggle uncontrollably.
"Mediocre talent, barely scraping by the key exam scores, and not studying seriously; if you keep this up and your scores fall back in the next monthly test, I'll call your parents in!"
"Sit down!"
Only then did Luo Xi dazedly sit down.
His desk mate nudged his arm and laughed, "Did you stay up all night playing games again last night?"
"Yeah, that game was quite fun."
