Cheng Mo didn't expect that he would see Ye Huai again in City C seven years later.
He said: "Momo, I'm back."
Once upon a time, in countless nights and thousands of dreams, he had dreamed of many scenes in which he and Ye Huai met again, but only that sentence 'Cheng Mo, I'm back' had never appeared in a dream.
Seven years is neither long nor short, but it is enough for me to stop loving you.
Ye Huai, I don't want you anymore.
Intention: acquaintance is fate, missing is fate, everything is fate.
