Zhi Bi

Since he started high school, Lu Jia has rarely called Mu Wenran “Big Bro”. Exceptions would be whenever he is lying or feeling nervous. Back when he didn’t want to do his homework, he would act sickly and say, “Big Bro, my head hurts” or “I understand everything in this chapter. I really do, Big Bro”. Yet now, 23-year-old Lu Jia will still cry in front of Mu Wenran. (Source: Bilibili Comics)
