Overview: Kōko suddenly falls ill and does not come to school for several days. When she does return, Banri notices she is dejected, but she denies anything is wrong, until she breaks down in tears and relays to Banri her fears that he might one day leave her. Banri reassures her he will not, and the spirit of Banri, who was observing, comments on a similar situation between him and Linda. In a flashback to the summer of their third year in high school, Linda tells Banri that she learned that her brother's fiancé was having an affair, and gets him to help her expose it. When the two photograph the affair, Linda has a change of heart and deletes all the photos, and instead confronts her brother's fiancé and tells her she will keep it secret, but to never let it happen again. Afterwards, Barni vehemently voices his disapproval of her decision, but apologizes when he notices how troubled she is by her own deceit. Banri comforts Linda by saying she is not alone, and he will bear the lie she knows with her, and will always find her and be there for her, but he fails to reassure her when she asks. In the present time, Banri and Linda meet and talk, where Banri mentions Kōko is sick again, while Linda mentions her family and brother. When Banri shows he does not remember she had a brother, a saddened Linda leaves, but not before she uses the words he used to comfort her in the past to encourage him to be there for Kōko. The spirit of Banri who witnessed this, regrets that he did not confess his true feelings for Linda in the moment she sought reassurance from him, and notes that it is too late for them. However the next morning, the spirit of Banri awakens to find himself back inside his physical body. (Source: Wikipedia)
