Xie Huanhuan has always felt that she is a "contradictory body" - in front of her parents, she is a sensible and docile good girl who hides her rebellion in a locked diary; in front of her best friends, she is a "little lunatic" who dares to speak out and dare to intrude, and can help her friends; in front of the senior Lu Yu who she has a crush on, she becomes a coward who is so nervous that she can't finish her words, and she has to muster the courage to even look at her.
In the summer when she was seventeen, Lu Yu accidentally glimpsed Xie Huanhuan's "versatility" during an unexpected campus charity sale. She thought she would be laughed at, but she didn't expect that the note Lu Yu handed over said: "You are all real in different ways." From then on, Xie Huanhuan began to slowly accept every side of herself as time passed, and gradually let go of her timidity while getting along with Lu Yu.
But growing up has never been smooth sailing. The expectations of her family collided with her own pursuit. Her friends' misunderstandings made her fall into confusion. The sourness and temptation of secret love made her toss and turn. Xie Huanhuan wrote these thoughts one by one in "love letters" to her future self. Each letter hides an unknown part of herself. It wasn't until many years later, when she reopened the yellowed letter paper, that she discovered that since the age of seventeen, Lu Yu had been responding to her sincerity hidden behind many faces in his own way. This is a journey of growth about self-acceptance, and a two-way rush hidden in time. Every imperfect aspect will eventually become illuminated by love.
