The night Li Meilin received a confession from her best friend Zhao Chen, she didn't know what to do or how to express her true feelings without hurting the other. But just as she was about to respond, Zhao Chen stopped her, saying that he would be willing to wait for her response.
That is what bothers Li Meilin the most. The more she makes him wait, the more it would be painful for him to accept the truth. However, since it is his wish to be like that, Li Meilin didn't have a choice then but let him be for now.
She could also feel him sensing what would be her possible response. Maybe is it because that Zhao Chen is afraid of facing the truth that is why he prefers it to be delayed for now?
Well, maybe this was just all inside her head. Only Zhao Chen knows the reason.
Later that evening when she was getting ready to go back to the Lim residence, she could still feel the growing tension and awkwardness between her and Zhao Chen.
