After beginning high school, Lu Jia rarely addressed Mu Wenran as "Big Bro" unless he was being disingenuous or anxious. In the past, when he wanted to avoid doing homework, he would pretend to be sick and say things like, "Big Bro, my head hurts" or "I really understand this chapter, Big Bro." Nevertheless, even now, at the age of 23, Lu Jia would still break down in front of Mu Wenran. Tearfully, he would admit, "I'm sorry, I don't like you, Big Bro." Although that was untrue, Mu Wenran would respond with a smile, wiping Lu Jia's tears away and whispering soothingly, "It's okay. I like you."
