On Monday, Kaori Fujimiya rejects Yuki Hase's proposal of friendship. Feeling disheartened, Yuki's friend Shogo Kiryu advises him to ask Kaori for the reason that they can't be friends. However, when he tries doing so, Kaori feigns illness and avoids him. On Tuesday, Yuki goes to the rooftop and sits down to lunch with Kaori, where she explicitly says that she cannot have any friends. Not giving up, Yuki compromises that they have lunch the next day as acquaintances only. On Wednesday, Yuki is held back by a meeting regarding his math results and is forced to arrive late to the rooftop. To his surprise, Kaori waited for his arrival before eating her own lunch. The two talk about the things they do with friends and after school. After having lunch on Thursday, Kaori excitedly shows Yuki a flyer for a crêperie but stops herself, declaring that they aren't friends. As they continue their discussion, Yuki asks for Kaori's view on friendship. Finally, as Friday arrives, Kaori tearfully explains to Yuki that she loses the memories of people she gets close to every Monday, leaving the latter in confusion and sheer disbelief. Unsure of how to interpret Kaori’s explanation, on Saturday, Yuki asks for Shogo's advice and he encourages Yuki to pursue Kaori. On Monday, Yuki approaches Kaori in class and heartbreakingly understands truth of her words when she looks at him with an indifferent and irritated expression, signifying her loss of memory. However, Yuki chooses to believe that Kaori wants a friend but hides behind a façade as a coping mechanism against being hurt from her amnesia. Thus, Yuki once again asks her to be friends.
2	"How to Spend Time with Friends." Transliteration: "Tomodachi to no Sugoshikata." (Japanese: 友達との過ごし方。)	April 13, 2014 (2014-04-13)[14]	[16]
Kaori immediately rejects Yuki's seemingly intrusive proposal, knocking the latter into a disheartened state once more. However Yuki picks himself up with encouragement from Shogo. The next day Yuki surprises Kaori on the rooftop and explains their lunchtimes from last week which Kaori happily believes. The following day, Yuki suggests that Kaori keep a diary to help her remember the time they spend together, and she begins documenting all the good and bad traits of Yuki's personality. On Friday Kaori presents Yuki with the crêpe flyer and he suggests that they visit the place after school. Kaori, shy of being seen together after school suggests meeting on Sunday instead. However, when they meet up, the crêperie turns out to be closed and Yuki suggests that they go to a karaoke place instead. After a fun-filled Sunday afternoon, they return home on the train, discussing how they will meet on the following Monday. A teary-eyed Kaori gets off her stop, asking Yuki to tell her all about today on Monday. That night Kaori creates a large notice on her bedroom door, reminding her friendship with Yuki and to read the diary for more details. At lunch on Monday, Kaori timidly meets with Yuki on the roof for the first time yet again and tearfully forces herself to remember him with her diary. Noticing that Kaori hasn’t remembered anything from the diary, Yuki apologizes for his selfishness for her to remember him and how it caused her unnecessary pain. To Yuki’s dismay, Kaori records Yuki’s unfair and self-centred nature within her diary. However, Kaori also writes down his attentiveness to her and his sincere apology, acknowledging him as a wonderful person. Yuki asks Kaori to be his friend and the cycle repeats once more.

Kaori begins making lunches for Yuki and records what he likes to eat. Afterwards Yuki suggests that they let Shogo in on her secret for an outside perspective. The following day Yuki has Shogo join them for lunch and his harsh demeanor slightly intimidates Kaori. However Shogo seems to understand when Yuki begins to explain Kaori's memory loss and even provides theories on how it may have originated, despite his skepticism which creates a small rift between him and Yuki when the latter defends Kaori. The next day after school, Kaori forgets the diary under her desk and finds herself scared to retrieve it in front of the other students, especially when two girls bring her to tears with their trash talk of her. However Shogo retrieves the diary for Kaori and explains that people won't understand her if she doesn't speak to them herself. The following Monday, Yuki runs after Kaori when she rushes out of class after a Math problem suddenly causes her to remember the eggs she made for lunch the week before. Shogo also follows them and since Kaori does remember him in the same manner as her family, deduces she doesn't consider them friends and ends up believing her story—with Yuki more optimistic than ever about Kaori's progress.

A rumor begins spreading around the class that Kaori and Shogo are friends. Finding himself a bit envious, Yuki upsets Kaori by asking her to tone down on inquiries about Shogo. However his words hit Kaori harder than expected, resulting in their first fight to which she leaves school early that Friday. Kaori eventually finds herself at the river where she accidentally loses her diary, while at the same time Yuki goes to Kiryu for solace. Kaori then collapses from a cold when she returns home, coincidentally knocking the reminder about her diary off her door. The following Tuesday, Kaori finally shows up for school and Yuki immediately attempts to apologize for their fight. However much to his shock, she fails to remember him or her diary. Feeling depressed, Yuki asks for Shogo's advice and his words encourage Yuki to begin searching for Kaori's lost diary. Afterwards Shogo speaks with Kaori and helps her realize that her memories are missing. The next day, Kaori visits the river on a whim and finds Yuki desperately searching for the thing she forgot.

Afterwards Kaori reveals her condition to Saki, with the latter likening it to her own casual forgetfulness, suggesting instead that Kaori not worry too much on it and the pair officially become friends. After school on Friday, Saki invites Kaori on a friendly date and they do much of the things that Kaori always wished to do with a friend, much to the envy of Yuki, who also drags Shogo along to observe them. At the day's end, Saki tells Kaori about how she used to be bullied but overcame her ordeal thanks to her friends; consequently bringing Kaori to tears when she acknowledges their true friendship. The following Monday, Kaori does indeed forget Saki. However when Saki begins prompting her memory, Kaori seems to recall a bit of their time together and enjoys their interaction, especially when joined by two of Saki's friends, Maiko Serizawa and Ai Nishimura.

Afterwards, Saki decides to head home despite not finishing her assignments and Shogo lends her his completed answer sheet which triggers a memory from their elementary school where he had also done this for her in the past.

Afterwards Inoue introduces a transfer student named Hajime Kujo, who finds a seat next to Kaori and upon noticing her, harshly brands her as a traitor for breaking their "promise."

After school, Kaori runs into Hajime and two of their elementary school friends, Ota and Yamasato, at the crêperie where she explains that she genuinely doesn't remember Hajime before some painful memories surface, causing her to run away in a panic. Just then, Yuki shows up and vents his frustration on Hajime before deciding to reveal Kaori's condition to him.

While there, Yuki asks Hajime about his past with Kaori and learns of their popularity and study sessions in elementary school, reminding Yuki of his current relationship with her. As Ota and Yamasato show up they explain that Kaori was bullied by her classmates led by her so-called friend Shigahara Naomi out of envy at her relationship with Hajime. This caused her to flee in tears and was subsequently hit by a car, thus missing her meeting with Hajime and resulting in her memory loss, much to Yuki and Hajime's shock. At the same time, Kaori hears the conversation and breaks into tears after which Hajime ends up blaming himself for her condition.

After school, Shogo warns Yuki that everyone else had noticed the rift between him and Kaori. As Winter break begins, Yuki inadvertently runs into Kaori at the bridge much to his surprise and they decide to take a stroll together.
