Gui Fa maintains a complete deadpan demeanor and is known to be extremely shy around others, as they prefer to cover their face with a book at all times to avoid making eye contact. According to Mei, Gui Fa was shy even in the past and has noted that it has gotten worse over time.  The only rare times Gui Fa is willing to show their face to others is if they were to become serious or would be in a situation where they would need to use their hands for other things.
