Gu Xijiu would rather avoid having a relationship if love could make someone lose their mind, or become anxious and insecure. Did he love her? That sounded easy but did he really? She suspected he had been telling many girls that he loves them.
The feeling of falling in love with someone which he described earlier sounded like a story from some novel, it was not real! Even if the emotion was intense, that was just the chemical reaction in the human body and brain, it would eventually fade away.
As an assassin, she only needed a calm and harmonious love. A safe and long-lasting relationship. She would not be overly attached to the man, hence, she would not feel it was the end of the world even if she loses her lover. She would not even feel ecstatic when she got her dream man.
