Lee Know

The locker aisle was almost empty when Lee Know stopped in front of what was now her locker. As soon as she opened the door, a white envelope fell at her feet.
Curious, he picked up the letter and glanced at the front of the envelope. There was no name.
Before she could even open it, she heard hurried footsteps approaching.
"This letter is not for you..."
Lee Know looked up, observing you, clearly desperate.
"He is sure?"
Without taking his eyes off you, he opened the envelope and began to read the first few lines.
A slight smile slowly appeared at the corner of his mouth.
"So... you were waiting for Bang Chan to open this closet."
He folded the letter carefully and put it in his pocket.
"I think you didn't notice. We switched lockers a few days ago."
He took another step towards her.
"Relax. Your secret is safe... for now."
His gaze swept over her face for a few seconds before she added, in an amused tone:
"But secrets have value. And, from today on, you'll owe me some favors if you want this letter to remain a secret. Otherwise... I could accidentally end up spreading some copies around the college. So it's best to give me your name and phone number now, so I can contact you when I need something."
He said, taking his cell phone out of his pocket to write down the number.
