I can understand where Fu Chenxi is coming from. She never had a confidence, courage, presence nor an outstanding background. But if you think with Gu Jingyan out from the picture, people can notice yyou more, you're wrong. Because Lu Beichen and Gu Jingyan's world are filled with people with charisma. You would still be in the shadow because you yourselves do not know how to carry yourselves in public.
Yes, both Lu Beichen and Gu Jingyan love to bicker with each other. They are sincere & truthful, and are so comfy with each other. Boss Xu & Little Q are adamant that Gu Jingyu attend the party, else they would be so bored - Fu Chenxi lacks personality. Gu Jingyan genuinely shares with Fu Chenxi. Ultimately, Beichen and Jingyan are truly fated to be together... and Chenxi is just a temporary partner.
