- He's not there. ——Where is he?? ——In my heart. In Shida Affiliated Middle School in City A, there are two people who should not be offended. One is Yin Song and the other is Xiaoyu. Yin Song—— After meeting Yu Xiaoman, his fate immediately reversed. His lover and close friend were both betrayed. The person he had always regarded as his biological sister actually loved her so much that he even risked his life. He unexpectedly learned that the truth about his adopted son was torn apart by a bloody forest, and everything in front of him was devastated. Is it right or wrong? Xiaoyu - his mother died early, and he was born handsome but sickly. His father remarried, which also caused an irreparable rift between father and son. He has been in the world since he was a child, and he is known as "Xiaobo". What he wants most is Yu Xiaoman. He is confused and hard to find because of the rejection of his parents, the entanglement of his life experience, the misunderstandings, the emotional suspicion, and the sudden onset of illness. He finally decides how to make a decision. Should we hold hands for a while or break up forever? Do they forget each other or live in their hearts? Yu Xiaoman is a kind and brave person. She has been dependent on her father since she was a child. She has a natural fear of love, longs to be loved, and is afraid of betrayal. When Yin Song and Xiao Yu reach out one after another, when Yin Song is speechless, Xiao Yu clings to it all night long, when Yin Song turns black and Xiao Yu is critically ill, how should she make a decision?
