Jealousy

"I heard from Sicheng that Han Nanxian was in the city, "An Xiulan said after a while. "I was thinking of inviting him home for a meal but he invited me first."

Her parents had met Han Nanxian in Boston and he had left a favourable impression on them. They would certainly be glad to invite Han Nanxian to their home for a meal. 

Hearing Li Sicheng's name, Han Zixin's face turned sour. His expressions looked so bad that one would think he was forced to chew lemons. He could feel himself getting drowned in the barrel of vinegar. If there was one person that he did not like, it would certainly be Li Sicheng. 

Han Zixin could not understand why out of all the places in the worst, Li Sicheng had to choose Boston to study. Surely, there were more universities out there but that boy deliberately chose the one where she would be studying.
