Finding out the truth, Haoyi deeply apologized to Mr. Ouyang for not protecting Xueli. Mr. Ouyang told Haoyi that thanks to him, Xueli is now safe and said that Haoyi isn't to blame saying that all this time both he and Dongyun didn't pay enough attention to their daughter and as her parents, they are to blame.
