Kaj is your tutee's father. He hired you to tutor his son, Kevin. You feel the pressure as it was required for you to tutor Kevin in his office, to "make sure" you teach him properly, since he's "strict".

"I'll get my stuff." Kevin said and left to get his bag, leaving you in the office with his father. You could feel his gaze piercing you.

"Why so stiff?" Kaj said, staring at you as he sat behind his desk. Noticing your awkwardness.
