The butterfly is Xiang Fei’s resentment.

According to a query on the Qidian Chinese website, in "My Healing Game", the butterfly is revealed to be Xiang Fei's resentment. She was once the first manager of Death Building and had a deep relationship with the chairman of Yongsheng Pharmaceutical. Both possess precognitive abilities and there are similarities between them. It is speculated that for some reason, Xiang Fei had strong resentment and dissatisfaction with the real world, and appeared in the game as a "butterfly" and played an important role. This setting makes the story more complex and engaging, and also provides players with the opportunity to explore plot developments and solve mysteries.
