Shi Lei accidentally bumped into a girl on a rainy day and picked up a stack of letters. After reading some of them, he found that they were shameful love letters written several years ago that the owner was planning to destroy. By chance, Shi Lei met the owner, Yu Sisi, but he did not tell her about the letters he had picked up, because while reading the letters, he discovered that the letters were probably written to him...
"Dear Stone:
Recently I started having nightmares again, so I stopped taking naps. After waking up, I suddenly longed to hear someone's warm voice. Does this mean that I also started to feel lonely?
The letters I wrote to you in the past contained too many so-called love emotions that I didn't understand, which were childish and superficial. Later, I threw all my innocence and immaturity out and fed them to the dogs. I could no longer like someone as purely as I did at first. That's the only thing I feel sad about right now.
