Hearing YuYan's shaking voice while asking who exactly he was made Li FuJin's body instantly frozen in shock. His heart almost stopped beating as he doesn't know how to respond.
Accompanied by her sudden question, it was clear that YuYan was not just remembering about 'Li FuJin, but also comparing to him as Zhou Ruegen.
He had guessed it because he was carefully observing all the changes in her expressions when they both remained silent after she asked if they knew each other before meeting in the forbidden forest.
Li FuJin decided to watch her silently after noticing that YuYan seems like she was suddenly in a daze, but he has no idea if it was due to a flash of memory or she was just thinking about something else.
What more was to see her blushing. Though he was not sure whether she was aware of it, Li FuJin had guessed that it must be about having intimate moments for her to looked embarrassed.
