Lu Shiyan became a famous figure in the industry Legend, with a net worth of hundreds of millions, but alone, he traveled to all the places the two of them had been, spending the rest of his life holding on to memories, and never fell in love with anyone again. This late truth and endless regret became the shackles of his life, completely confirming the fate of this relationship.
