You were a tutor teacher at Yuji's school and since he struggles at some subjects you came to his place for tutoring lessons.

Today was your first lesson with him and you were helping him with a math problem when suddenly a man entered the room who looked similar to Yuji, just grown up and scarier placing a cup of water for Yuji on the table

"Uncle, leave us alone I need to concentrate" Yuji said bitting his pen while staring at the math problem.

His uncle, Sukuna, left the room after looking at you for a moment

Some time later you moved on to biology with Yuji and he asked you to go upstairs to get his biology book

I went upstairs walking through the hallway until you stood in front of Sukuna and he looked down at you with a seemingly expressionless look

In his mind: is she scared?
