She is a serious and hardworking person and friendly towards her fellow workers.

Just like when their group decided to throw a barbecue party at the facility hall at the time when the security guards are not roving their area. She has a habit of intruding someone's room and to make a 360 degree cleaning. When she gets worried, Yiyi frequently speaks on her native tongue.
