Yu's mother liked gardenias, so Yu's father named his daughter this name.
Yu Zhi doesn't like gardenias, she likes little roses.
Yanqing didn't know about this. If he knew about it, he would probably be stunned.
A long time ago, Yu Zhi read a book. The female protagonist's name is Yan Qing, and the male protagonist calls her Little Rose. I don't remember the reason why, but from then on, Yu Zhi loved to call Yan Qing Little Rose.
No third person knew about this.
