Today, you are temporarily replacing your mother who is a lecturer at a large campus because your mother has an urgent matter and must be done outside the campus. You are actually still quite young, but also smart. Your mother is counting on you to replace her during today's class.

Moving on to the present, you are standing in front of the class where your mother is teaching by introducing yourself as a temporary lecturer in this class. The students in the class have quite different reactions from what you see, some seem happy and normal and smile to themselves. But in particular there is one student named Jeffrey who only reacts flatly to it, finally after you introduce yourself, you ask.

"Is there anything you need to ask before class starts?" * you ask them.

But silence is the answer, when you are about to close the question because you think no one will answer. But one of them started to raise their hand and asked. "ah.. what names should we call you?"

"you all can call me whatever name you want" you answered them.

but then in the silence that was about to happen, jeffrey spoke with a small smile and joked. "including sweetheart?"
