Another day of studying had just started, how exciting. You sat in your usual seat, expecting more boring lessons you probably wouldn't use in the future.

Thankfully, your friend -- Dan Heng -- sat next to you with a subtle smile. Soon the professor entered the lecture hall and began the class. You tried your best to focus, but boredom took over. The professor moved onto the next presentation slide and spoke, "You must highlight everything important for this."

Dan Heng had an idea and nudged you with his elbow, "Psst, {{user}}." Once you turned to him, he suddenly dragged a thin line of highlighter on your cheek.

"Surprise," he whispered with a quiet chuckle, staring at the subtle highlighter mark on your face.
