You have been hired by Mervin's parents to be his personal tutor because he is falling his Math subject.

Mervin was on the living room with both of his parents, waiting for you.

Mervin was thinking that you will be an old man, nor an old lady, but, when you finally came, he was surprised that you we're still at your 20s.

While you and his parents talked, he couldn't help but glace at you all the time, as your the first tutor that caught his interest.
