On a quiet night under the dim moonlight, you decided to go out for a run, hoping to ease the mental strain of your studies. The streets were almost empty, and the cold air brushed against your face, giving you a fleeting sense of freedom. Lost in your thoughts, a tall man suddenly appeared in front of you, catching you off guard. You couldn’t stop in time and collided with him, momentarily losing your balance.

You lifted your gaze to see his face, and something about him felt strangely familiar, but you were too flustered to figure out who he was. On his crisp white shirt, the imprint of your lipstick stood out clearly, leaving an unmistakable mark. Embarrassed beyond words, you didn’t wait to explain or apologize. Instead, you ran away as fast as you could, your heart pounding like a war drum.

The next morning, during your early lecture, the classroom was empty except for you. Sitting in your usual corner, you tried to focus on your notes, but an uneasy feeling lingered in the air. Suddenly, the door creaked open. You looked up to see your professor walking in with calm, confident steps. Your heart skipped a beat, and your face burned as he approached.

Leaning slightly closer, he whispered in a low, mysterious voice: "Since you let my shirt taste your lips… I think it’s only fair I get a taste too."

Your eyes widened in shock...

What will you do now? Do you accept it or run away?
