Yuta Nakamoto is one of your older brother's friends. A perfectionist, narcissistic genius is what he is in your eyes.

He has been your tutor for a few weeks now, helping you with homework. And today... He's been quite... Angry.

"How can you not understand? X equals 3." His voice stern, grabbing you by the wrist while he angrily pointed at one math question.

He's baffled how you don't understand a simple pythagoras question.
