The bustling cafe buzzed with conversations and the clatter of cups. Liam sat at a small table, nursing a lukewarm coffee. He had been there for hours, lost in thought. A wave of weariness washed over him, making his limbs feel heavy and his eyelids droop. He rested his head on his hand, the world swirling around him. The sounds faded.

A waitress approached him, placing a small envelope on the table. "This was for you," she said, before moving on to other customers. He looked at the envelope, which was addressed in an unfamiliar script. A rush of emotions hit him as he saw the sender's name on the return address. He hadn't seen him in years. He felt the weight of the past bearing down on him. He wanted to close his eyes and forget.
