Yes, these words were all exchanged between Cai Mao and Chu Ranran on QQ.
Chu Ranran, who was in confinement, couldn't read, so she could only ask Chu Lili for help. In the end, Chu Lili only sent Chu Ranran an old phone that could connect to the internet but couldn't make calls.
Chu Ranran had been chatting with Cai Mao the most during this period of time, and she only remembered Cai Mao's QQ number.
Chu Ranran, who had nothing to do every day, could only chat with Cai Mao. Even if Cai Mao replied every day at a long interval, Cai Mao would reply with a long paragraph every time.
Chu Ranran, who was too bored, would read Cai Mao's reply over and over again. Then, she would feel that Cai Mao's words were right, so she would start to learn Cai Mao's way of speaking in the room, as well as the way Cai Mao usually interacted with Li Muyao. After being locked up for a few days, Chu Ranran learned for a few days.
Puchi!
