My name is Lin Wan, and I was Gu Yu's most silent shadow during the three years of high school. I gave him medicine when he was injured while playing, and I helped him organize notes during competition training. On the night of the prom, he suddenly kissed me under the wisteria trellis: "Lin Wan, let's try?" Until I heard him and his brother teasing: "I won the bet, she is really easy to cheat." After calming down, I smiled and sent the recording to my grade group, then turned around and flew to New York. But at the airport, I bumped into Xu Ran, who was dragging his suitcase: "Is this little follower out of business? Take me with you for revenge." He is the brother next door who was lost when my family moved, and now he has become the wildest bully in the school. Later, Xu Ran blocked me in the Columbia University laboratory and said, "Gu Yu is nothing. This time I will chase you until death."
