Plot
Misaki invited Senpai into their house, offering him some snacks and revealing him that her little sister talked a lot about him. She also asked if there's anything he wanted to know about her, stating that she would reveal him whatever he want regarding her sister. Before Senpai could make his question, Nagatoro entered the kitchen yawning, with messy hair and a comfy pj, blushing in embarrassment after discovering that he was there and thus immediately wenting to dress and do her hairs, scolding the boy for not having called nor warned her before coming to her house, to which he replied that he sent her a text, although she yelled back at him that she was sleeping. Then Nagatoro's sister prepared her a special marlowe pudding with fruit and cream to calm her down, saying that they should all sit and chat a little. However feeling ashamed, Nagatoro asked Senpai to came to her room and forbid her sister from entering. While in her room, Nagatoro blushed a little and thanked Senpai for coming to visit her, to which the embarrassed boy replied he simply wanted to bring her printout. Then, they started eating pudding and, at some point, the girl teased him by offering to feed him. Due to being alone with her, Senpai decided to play along with it and opened his mouth, right in that moment Nagatoro's sister enter and caught them in said compromising position commenting the boy does indeed seem interested in "every little detail" of her little sister. Blushing vividly, Nagatoro sent her sister out of her room, then she asked Senpai what does she meant by her last sentence.

After Misaki's statement an awkward silence descended on Nagatoro and Senpai, prompting the boy to trying to leave right after finishing his pudding, however Nagatoro prevented him from doing it asking him to play a match with a videogame with her like they did the last time he went to her home. While playing the game, Senpai noticed that Nagatoro have probably practiced with it, since she has gotten better. Then, the girl asked him what did he talked about with her sister, worried that he asked her about her secrets while she was sleeping, however he quickly reassured that he wouldn't have poked his nose into someone else's business without asking. Hearing this, after winning a match, Nagatoro offered to reveal him one of her secrets of his choice if he managed to defeat her. At first Senpai pretended not to be interested, slightly offending Nagatoro, then he accepted said offer saying he was simply "taking her up on that". After the match started, Nagatoro playfully teased him asking if the secret he wanted to know was her measurements or something "even lewder", to which Senpai replied he would have liked to know her first name, leaving her speechless.

A bit embarrassed after realizing that she never told her name to Senpai, Nagatoro blushed but then tried to act nonchalantly saying that she didn't mind to tell it to him but provocatively asking him why he wanted to know it. The boy lied telling her that it was simply because it would be easier to call her, to which she replied that how she called her didn't really mattered, however, while they were talking the game's time runs out resulting in Nagatoro's loss. Nagatoro played it coolly - despite being visibly happy of the circumstances - and, using their previous bet as an excuse, get ready to tell her name to Senpai; however the boy he stopped her at the last minute saying that he didn't want to know her name due to having won a game but rather after finding the courage to asking it to her directly. Both Nagatoro and Senpai blushed and agreed on waiting for that day to come. Right at that moment, Nagatoro's sister stormed into the room calling her "Hayase" and bringing the photo album of her primary school years in order to show it to Senpai. Regardless of Nagatoro yelling her to getting out of her room, her sister continued to show embarrassing pictures of "little Hayase" to Senpai. That evening, after they said goodbye to one another, Nagatoro told Senpai that she would have been back to school the following day and suggested him to "prepare himself", causing the boy to smile heartily.

Later, while returning home, Senpai thought back at the girl's name, smiled and started to run.

In a post credit scene Nagatoro, back to school and in full health, offered to pose for Senpai in order to "thank him" and suggested a new pose by lifting her skirt a little, however the boy quickly dismissed it as being too much, subsequently being mocked by the girl, who then proposed to pose in a Bruce Lee-esque kick instead. Senpai accepted and started to draw her, however she soon started to tremble and, due to her legs having gone numb, she fell right on top on him. Standing up, Nagatoro asked him if he protected her intentionally, which he replied he didn't, evidently lying and causing Nagatoro to blush and playfully tease him.

Trivia

 * This episode is the adaptation of Chapter 60, 61, 62 and Bonus 11, however there are a few differences:
 * The opening scene of the episode shows Misaki went to the kombini to buy a cup of pudding for her sister, while in the manga she simply mentioned having done it and first appeared while back in her courtyard.
 * In the anime, when Senpai walks back home while thinking about Nagatoro's name, it is shown a brief glimpse of Nagatoro and Misaki looking at the family photo album, while in the manga the scene is completely white.
 * When Misaki shows Nagatoro the pudding that Senpai brought as a gift, in the manga Nagatoro calls it "Marlowe Pudding", while in the anime, she calls it "Lawman Pudding". The pudding container also has a slightly different logo from the manga version.
 * In the post-credit scene where Nagatoro holds a kick as Senpai sketches her, in the anime Senpai and Nagatoro are both wearing sweaters while the manga shows them in their regular uniform shirts.
 * The pudding that Misaki bought at the convenience store is modeled after Gilco Pucchin Pudding.
 * The "Lawman Pudding" that Nagatoro becomes excited about eating is a reference to Marlowe Pudding, a Japanese brand of pudding known for its use of high quality Japanese ingredients and features an illustration of fictional private detective, on its containers.
