Everyone has a youth that is either unbridled or passionate. She is the most colorful character in our lives. It is at this time that our outlook on life and values begin to change. Of course, our outlook on love also begins to sprout and mature during this period. I think every one of you who is in your youth, or who has stepped out of your youth, will have an experience like Su Xiaoxiao. Secret love is the most soul-stirring love. I would like to write this document to everyone who is in secret love or has had a crush on you.
