He (Han) is gentle and considerate, but he and she (Shu) fell in love with the same her (Lin) at the same time. Later, he met her (Bei) at Yinyaga College, but he mistook her for her (Lin). She (North) was used as a substitute, shuttling back and forth between two men, but at the same time she fell into the danger of being exposed to two men. Her (North) life will no longer be peaceful... Declaration: Shu: "Stupid idiot, I want to tell you that you are no longer a substitute. I really love you. No matter what happens, I will always love you and protect you!" Han: "Ran Ran, I'm sorry for mistaking you for her (Lin). I will give up on you because I have never loved you at all, but I still want to protect you!" (Sorry, this is supposed to be a youth campus novel, but I didn't realize that it was written as a time travel novel. Sorry... Hee hee...)
