The protagonist begins work as a trainee teacher in an all-girls school, where he has a strange dream about turning into a monster and ravaging an angel. Whilst discussing his disturbing dream with the school nurse, he encounters a student who looks just like the angel from his dreams. The two become close, and attempt to find an explanation for his strange dream. However, in reality, the protagonist is not a trainee teacher, but has instead been sent to a mental hospital, with the vast majority of the cast being mere delusions. The game takes place from the perspective of the protagonist, who is an unreliable narrator, and progresses as the player selects students to converse with, which sheds light on the many delusions of the protagonist.

The producer Kenzo Nagaoka explained that at the time, Kanon had been a huge hit, and thus he had been instructed to make a bishōjo game by the head of Visual Arts. Nagaoka felt that most of the games at the time felt derivative, and so wanted to create something with a unique angle, with themes of "eternity", "ethereal girls", and "deep emotions", essentially constructing something new from the essence of Kanon.
