Hua Hua was actually Su Yurou's desk mate, as well as one of Gao Jun's secret admirers. However, aware that she wasn't a match for Gao Jun, her love had always been silent and unrequited. Gao Jun knew about the girl's feelings for him and exploited them, having her get close to Su Yurou so that she could report back on everything related to Su Yurou.
"Hello! Gao Jun, is that you? Hehe, do you need something from me?" Once the call connected, Hua Hua seemed very happy. In her eyes, although she couldn't have Gao Jun, just being able to hear his voice was a source of great happiness to her.
Yet Gao Jun's face was one of indifference as he said, "Hmm, do you know about Yurou's transfer from school?"
"Ah?" Hua Hua was clearly surprised and asked, "Really? Why would she transfer schools?"
"If I knew, why would I come asking you?" Gao Jun said with a touch of impatience.
