"Dad, I tell you, I don't need a mentor!"
Silva sighed, "Killua, have you seen your grades? I mean, you got a D in English, that's one of the easiest subject and yet you still failed."
"Then I'll study harder!"
"You've already said that like 5 times this month and you still haven't improve."
Killua was cut off by a knock on Silva's door.
"Come in." Silva said.

"See?" Silva raised an eyebrow, "now go to your study room at once."
Killua rolled his eyes and groaned, "Fine.."
