When the weather is bad, Kaori and Yuki eat lunch on the stairs. Even though they are careful to return to class separately, Kaori is confronted one day and asked if she and Shogo are friends. She doesn’t answer, so Shogo is asked and he admits that they are indeed friends. Wow, Yuki is upset. He tells Shogo that he hates him.
Yeah, Yuki is upset supposedly because Shogo’s friendship was recognized before his. But in fact Yuki is just jealous since Kaori remembers Shogo and not Yuki every week. But if Yuki doesn’t say anything, things will never change. For Kaori’s part, she only hopes that Shogo isn’t mad about the rumors going around the class of them being friends. Yuki joins Kaori on the roof for lunch, without Shogo this time.
Kaori tells Yuki that because of him, she’s finally having fun at school. But when she mentions Shogo, Yuki changes the subject. I can see Yuki getting jealous when Kaori continues talking about Shogo. She knows so much more about him than she remembers about Yuki. I can see how Yuki would feel about that. He’s had enough and asks Kaori if she has feelings for Shogo. Kaori denies it, but Yuki still thinks she likes Shogo and it bothers him. He’d rather talk about them.
But Kaori begins to cry and calls Yuki an idiot. Saying that Yuki doesn’t understand why she wants to talk about Shogo, she leaves the roof. Not only does Kaori leave Yuki on the roof, she goes home as well. Yuki has really hurt her this time. Kaori ends up in a slight accident and loses her diary when her bag falls. In the meantime, Yuki has returned to class and tells Shogo that he made Kaori angry with him. His eyes fill with tears. It’s Friday and he doesn’t know how to fix this.
Kaori returns home, soaked by the rain, and comes to the conclusion that friendship is hard. She goes to get the diary from her bag and ends up fainting instead. The note she keeps on her door to read the diary also falls off. Sick with a fever, she spends the weekend in bed and by Tuesday, she still hasn’t returned to school. Yuki is worried and blames himself for Kaori getting caught in the rain.
When Kaori finally does walk into the classroom, Yuki drags her back out and apologizes to her. He also mentions her diary and introduces himself. But Kaori has no idea who he is. Yuki thinks she’s playing around, but soon realizes that she isn’t. Yuki asks her about the diary and is told that she doesn’t keep one. Besides, the only person she talks to at school is Shogo. That just killed Yuki. He must think that Kaori was so mad at him, that she must have hid the diary from herself, so she would forget him. Telling Yuki to leave her alone, she goes back to class.
Yuki has no idea what to do, so he turns to Shogo for help. He even makes Shogo cut class with him in order to discuss it. Yuki does think that Kaori threw away the diary, but Shogo wonders if she just lost it. Shogo berates Yuki for thinking that Kaori would be so heartless as to throw away her precious diary. This finally makes Yuki realize that Kaori would not have thrown it away, and he knows she had it with her when she left school on Friday, so that means she must have lost it on the way home. Yuki runs out to look for it.
At lunchtime, Shogo joins Kaori and although she remembers him, she doesn’t remember making eggs for anyone. Kaori kind of remembers having lunch with Shogo the previous week, but the memory is unclear. Shogo asks her what she did after school that week as well. She remembers someone going to get something she had left in class, but can’t remember what exactly it was when Shogo questions her. Shogo can see hard this must be for Kaori now.
Kaori feels that she’s forgetting something important. Shogo tries to nudge her memory, but tells her not to force herself when her head begins to hurt. He’s about to tell her what she forgot, but Kaori tells him that she needs to remember it on her own. Shogo wonders where the important thing is and says that Yuki is out looking for it. Shogo tells Kaori that she should talk to Yuki because it would make him happy. On the way home, Kaori sees Yuki running around and tries to talk to him, but he doesn’t see her, so intent is he in his quest to find her diary.
At home, Kaori’s mother finds Kaori making lunch for her friend. But Kaori seems confused about it. Yuki is not in class the next day and Kaori ends up on the roof alone. But she remembers something! She goes running back to the river and the spot where she dropped her bag. There she finds Yuki searching through the grass, and asks him what he’s looking for. She tells him that something important is missing from her memories and wonders if he’s looking for the same thing. Yuki says that he hopes they’re the same and Kaori offers to help him look. Yuki won’t let her, saying that it’s dangerous, but he does ask her if she could have thrown away her important thing. She still can’t remember what it was, but is certain that she would not have thrown it away.
That makes Yuki very happy, and Kaori sits on the steps as she watches him search the grass. When Yuki falls, Kaori runs to him, calling his name. That pleases Yuki as well, but Kaori isn’t sure why she called his name. And in the spot he fell, his hand touches the diary. He brushes it off and hands it to Kaori. She hugs it to her and Yuki asks if she will read it, but she tells him that she doesn’t need to. She reaches out and taking Yuki’s cut and bruised hand in hers, lays it against her cheek. Yuki is happy that they’ve made up. And Shogo is watching them from the bridge. I’m glad he was so concerned. I suppose he’s good for more than just sleeping through class after all.
Kaori hasn’t opened the diary yet, but I can only imagine it’s condition. It fell out in the rain and was sitting in wet grass all night. I wonder if it’s even readable. Perhaps Kaori will have to start all over again. At least Kaori and Yuki survived their first fight. And Yuki thinks it’s brought them closer together. That can only be a good thing.
