When the heroine checked into the hotel in the first episode, she did not specify what kind of room she wanted. However, according to the plot, the heroine was attracted by a mysterious hotel and finally chose a room called the "Ghost Room". The room was said to be occupied by a ghost and was considered one of the most suitable places for supernatural activities. However, the specific reason and actual situation were not described in detail in the novel, so it was impossible to determine whether this was a real guest room or just a fictional hotel name.
