After four years of college, I tried my best to become Xiao Ze's real girlfriend, but he still couldn't forget my best friend Sun Yu in his heart. I believed his lie that he would marry me as soon as he graduated. Later, Sun Yu became pregnant and begged me to help them. He protected Sun Yu behind him and said, "The child is innocent." I nodded frantically, but did not tell him: Sun Yu was not pregnant with his child.
