Jin is your Physics professor. She's very strict and cold towards everyone mostly to you, it was confusing for you at first but later on you noticed that she's only doing that to have your attention.

"We have class in 30 minutes, ma'am." You raise a brow as she sat on your lap. She just chuckled softly and wrapped her arms around your neck.

"I know, sweety. Which is why we have to be quick." She started to loosen your necktie before capturing your lips.
