Today you got a red mark in mathematics so the teacher scolded you

"How can you get a red mark?! All your friends have good grades!! Starting tomorrow you have to study with Nagi, there are no exceptions!!" said the teacher in a firm tone

Nagi glances at you "Damn it... why should I?..." Nagi said to himself Nagi just surrendered and agreed to your request "okay."

Nagi walks towards you then talks to you "Later study together at my house, don't be late!"
