Haruka Nogizaka's Secret

Yūto and Haruka continue to get closer, while Shiina's feelings for Yūto grow stronger. A meeting to plan for their school trip to Hokkaido is held at Yūto's house, but it soon devolves into a party. Afterwards, Shiina decides to confess to Yūto during the trip. In Hokkaido, Yūto and Haruka spend their free time together, albeit accompanied by Mika, Hazuki, and Nanami, who have tagged along. At day's end, Haruka tells Yūto that she had fun and asks him if they can have another date, which he happily agrees to. Once they return to the hotel, Shiina takes Yūto out into the city and she confesses that she loves him. Haruka, who had followed them, overhears the confession.

Yūto is unsure of how to respond to Shiina's confession, while Haruka is confused about her own feelings for Yūto. When Mika, Hazuki, and Nanami learn of her plight, Hazuki tells Haruka that they cannot help this time because Haruka must determine how she feels about Yūto on her own. Haruka tries to speak with Yūto, but is unable to do so and is left in tears when Shiina pulls him away. After spending the day with Shiina, Yūto comes to realize the depth of his feelings for Haruka, and parts ways with Shiina to look for Haruka. When he finds her, he confesses his love for her and Haruka reciprocates. They officially become a couple, while agreeing to keep their new relationship secret between themselves. After returning home, Haruka asks Yūto if they can form a doujinshi circle for the upcoming Summer Comiket, and he agrees to it.

Yūto and Haruka make progress on a scenario for an anime game. They present the completed game at Comiket. Nobunaga then shows up saying that three girls were looking for their stand. When Yūto and Nobunaga arrive with the three girls, Haruka freezes. The girls turn out to be her former "best friends" from when she was in middle school. They have come to apologize for turning their backs on Haruka when her secret was exposed back in middle school (even admitting that they like anime too); Haruka forgives them. As they talk things out, it is revealed that Setsugetsuka Tennouji, Haruka's archrival, influenced everyone to isolate Haruka. Later that night, after their game sells out thanks to Nobunaga's advertising, Mika calls Yūto and informs him that her sister is missing. Just as Yūto is about head over to assist in the search, Akiho calls Yūto that she knows where Haruka is and she is safe, but she is getting married the next day!

After Yūto Ayase returns an anime magazine to the school library, he accidentally runs into the most popular girl in school, Haruka Nogizaka, and discovers her secret that she is an anime and manga otaku which greatly distresses her. Haruka starts avoiding Yūto at all costs which causes others around them to blame Yūto for doing something bad to her. Eventually, Yūto finds Haruka on the school roof where he explains that he will not tell anyone about her secret hobbies if she does not want anyone else to know. This makes Haruka very relieved and happy that if anyone had to find it that it was Yūto.

Yūto and Haruka start spending more time together, such as walking to school together, which causes their peers to get annoyed that Haruka would be hanging out with someone like Yūto. Haruka asks Yūto to accompany her to Akihabara on Sunday and he agrees. The two spend most of the day going from store to store looking at the goods but not buying anything, though Haruka wastes some money on a toy vending machine. Yūto and Haruka even go to a maid café for lunch where Haruka is dressed in a pink maid uniform and gets her picture taken with Yūto. At the end of the day, they discover the handheld gaming console Haruka had intended to buy was sold out for now. This distresses Haruka, but Yūto cheers her up later by assuring her that he had a good time today with her.

The day before a test, Yūto comes over to Haruka's mansion and meets her younger sister Mika and two of her maids, Hazuki and Nanami. The next day at school, a guy bumps into Haruka which causes her bag to go flying which also exposes the Comiket catalog she had. Yūto manages to make everyone believe the catalog is actually his and Haruka only picked it up, though after this Haruka does not come to school for three days. He goes to see her where he finds out from Mika how her secret was exposed during middle school and she had to transfer schools due to being isolated from her peers. Yūto assures her that he will never leave her which relieves her so much that the next day she affirms after a short conflict that the catalog is actually hers.

Yūto has lately been watching one of Haruka's favorite anime, Nocturne Girl's School Lacrosse Club. Yūto and Haruka along with several others are invited by Shiina to go to a hot spring in the mountains. Haruka is especially excited since this is her first trip with friends, due to having her hobby of watching anime being exposed in junior high school. Haruka's maids and her younger sister Mika also come along, as well as Yūto elder sister Ruko and Yūto's teacher Yukari Kamishiro. When everyone is out in town, Yūto finally manages to tell Haruka about an event close by to meet the voice actress of the lead character from Nocturne Girl's School Lacrosse Club. Nobunaga runs into Yūto and gives him two tickets for the event, as he did not know he had to buy them beforehand. Haruka enjoys the event and treasures it as a precious memory.

Yūto and Haruka begin making a dōjinshi together, though Haruka's skill in drawing is still lacking. Nobunaga asks Yūto to cover for him selling dōjinshi for one of his friends' dōjin circles at an upcoming event for Nocturne Girl's School Lacrosse Club. Yūto asks Haruka to accompany him, who is overjoyed at the prospect of helping out an already established circle. Yūto and Haruka continue their work on Haruka's illustration book of the Nocturne Girl's School Lacrosse Club lead character Haruna, though the day of the event Haruka's book is not selling. Nobunaga gives Yūto some advice, telling him that half the enjoyment is actually making the dōjinshi and Yūto realizes there are more important things that the book selling or not. Yūto goes back to Haruka and starts promoting Haruka's book, and eventually three people end up buying it.

After finding out that Haruka is working to get him a Christmas present, Yūto decides to apply for a well-paying job as a part-time butler. He gets the job, but he must unfortunately serve the selfish and demanding Tōka Tennōji, a girl one year his junior, whose previous part-time butlers quit after a day or less at her command. Yūto has his work cut out for him, but soon finds that there is more to Tōka's situation than he initially realized. Through kindness and hard work he manages to gain Tōka's favor, but a certain situation results in damages that cost him nearly all of his pay.
