I'm Sorry, I'm Many Years Late

Sixteen-year-old Gu Xingzhi met Lin Wan, who was one year behind him, because of a math problem in which he missed a negative sign. From a reliable senior to an old acquaintance who lost contact, they reunited across a long period of time and finally fell in love. Gu Xingzhi was full of love, but he was clumsy and slow and did not know how to heal the accumulated loss in Lin Wan's heart. Disappointed and exhausted, Lin Wan quietly left the show. A farewell without saying goodbye became an insurmountable gap between the two. After years of separation, Gu Xingzhi has always been trapped in guilt, quietly waiting for an apology that failed. Reunion after a long absence brings back memories. There is no reconciliation, no continuation of the relationship. There are only two sentences that are many years late—— "I'm sorry."
