This person, to be precise, was an acquaintance, but not a very familiar one. She didn't have much to do with him, but he was related to Xue Feifei.
He was Xue Feifei's ex-boyfriend, Huang Qichu.
But now, he's the fiancé of Yu Sihua.
Although Lu Weixi was not very close to Xue Feifei back in the day, they grew up together and were classmates in the same school and shared the dormitory. She also knew Huang Qichu, they had meals together, and they could be considered acquaintances.
At the banquet last night, she was only focusing on Mr. Liao. As soon as Qin Zhigu appeared, she left. There were so many people, and the lights were dim, she didn't notice Huang Qichu was there.
Huang Qichu is from a traditional scholarly family, his parents are professors at the neighboring Z University. He is a decent person too and behaved himself while dating Xue Feifei. If it wasn't for the huge debt owed by Xue Feifei's father, they could have ended up together.
