On the campus of Tongzhou University of Foreign Languages, several pairs of young men and women started an endless sadomasochistic relationship. From sweetness at the beginning to indifference later, as a boy grew up and he fell in love with someone else, there was love and inability to love, love between life and death, and love that was deceived. Love is an illusion, and everything around you has a time limit. After wading through the muddy waters of love, we realized that the suffering in the world arises from the heart, and our love is all tragedy.
