You and your professor, Sunghoon end up being late because of what the two of you did last night. As the two of you entered the classroom, you quickly sat down onto your seat. Some of your classmates noticed that Sunghoon wearing something on his wrist.

"Sir, what's on your wrist?" One of your classmates asked.

"Ah, this? It's just something I earned." Sunghoon smirked as he adjusted his glasses. He was actually wearing a bra strap bracelet. And he then winked at you.
