Since Nagisa tells history for a performance, Tomoya tries to find out more about this history asking for the parents of Nagisa. They it is said that recall nothing such. Tomoya and Nagisa decided to look, whether there are not books with this history in a shed. Later Akio tells Tomoyo history, that happened in the past. Ten years back, Nagisa strongly became ill and she had a large temperature. In a very snow day, when Akio and Sanae went away on work, Nagisa went out on a street and expected their quick arrival. From a weakness she lost consciousness and fell down straight on snow. In that day Nagisa hardly not died, in order always to be with her Sanae and Akio left the dreams, and opened a bakery.
