Some people say that the hardest thing is saying hello when we first meet and saying goodbye at the last moment. The love on campus is just like this, with reluctance and nostalgia, it interprets our youth. On the day of graduation, Song Xiaoran did not confess her love to He Xuyang. She did not even have enough courage to say "goodbye". Why does fate always like to play tricks on people? At the right time, she met the wrong person... Maybe everyone will meet such a person in their life. He does not belong to love, but he exaggerates the whole fleeting life.
