Zhou Yuchen actually had a lot of questions to ask Yun Liuli, but he was never a good talker.
He was worried about Yun Liuli and was even more worried about the guy she liked. This guy seemed to be much older than her, and age gap aside, he was worried that this guy had used improper means to have her wrapped around his little finger.
Although Yun Liuli didn't love him, he couldn't let the girl he loved get hurt.
Guan Nina was outgoing and talkative. On the other hand, the older Jacob Bellucci was quiet and reserved and seemed like he was a man of few words. Hence, Guan Nina didn't dare to ask Jacob Bellucci questions and instead talked a lot about Yun Liuli's excellent performance at school to liven up the atmosphere, as well as help Yun Liuli pursue Jacob Bellucci.
