"Sir?" The cashier, who had also reached out to pick up the dollar bill, quizzically looked up at Gu Yusheng.
As if he hadn't heard anything, Gu Yusheng brought the note up to eye level.
The dollar bill must have changed hands many times, as it was old and the words on it had started to fade away, but it was sufficiently clear for him to read.
The handwriting was neat and appeared to be less mature than what it looked like now, but Gu Yusheng was dead sure that it was his handwriting after scrutinizing it for a few seconds.
There were only five words on it—five simple words.
Yet he stared fixedly at them and, one word at a time, silently read them out in his heart a few times before he managed to piece them together in a complete sentence.
"Sweetheart, I am really sorry."
Sweetheart, I am really sorry…
Sweetheart… From A's letter, he realized that that was his nickname for her in high school.
Sorry… Was I apologizing to her?
