Since he started high school, Lu Jia has rarely called Mu Wenran âBig Broâ. Exceptions would be whenever he is lying or feeling nervous. Back when he didnât want to do his homework, he would act sickly and say, âBig Bro, my head hurtsâ or âI understand everything in this chapter. I really do, Big Broâ. Yet now, 23-year-old Lu Jia will still cry in front of Mu Wenran. While crying, he said, âSorry, I donât like you, Big Bro.â He lied. Mu Wenran smiled and wiped Lu Jiaâs tears, before saying softly, âItâs alright. I like you.â
