Watch Haruka Nogizaka's Secret

Yūto is invited to come with the Nogizakas to a ski resort in the mountains. He thinks it is just for them but he quickly finds out the entire class is coming on this trip. While the group enjoys all the hot spring resort has to offer, Shiina sees the trip as an opportunity to express her feelings to Yūto—but in an attempt to hug him, she ends up groping Gento, who was covered in sheets. An enraged Akiho catches them in a compromising position and gets the wrong idea, causing Gento to pass on the group's shrine visitation the next day. The next evening, a blizzard arrives and Haruka goes missing on the top of the mountain. When Yūto, equipped with an insulated polar bear suit, finds her, they both fall down a ridge and become stuck in a cabin. As she is wet and freezing, Haruka takes off her clothes and joins Yūto in his bear suit in just her underwear. However, the two are quickly found not only because the bear suit has a tracking device, but also because the cabin turns out to be just behind the resort.

Yūto has to make a tough decision of whether to stay with Haruka or leave her so she can become an idol. Yūto asks Milan to attend her concert on Valentine's Day. During the concert, Yūto, with some "on-stage prodding" by Milan, decides to leave so as to go to Haruka's audition. Shiina is worried about Yūto and Haruka's relationship. Yūto decides that he wants to stay with Haruka and it is finally revealed to the unaware Haruka how Yayoi had planned to make her into an idol. Yayoi and Nozomi try desperately to stop him, but Haruka's family and maids help to get the upper hand against them. The final blow comes when they are later forced out of their talent agency after Haruka's father buys it and all associated material from them in a hostile takeover. Later at the Nogizaka mansion, as Akiho and Gento watches Yayoi and Nozomi in some mud wrestling contest on TV, Haruka gives a Valentine's present to Yūto.

During the New Years break, Shiina expects something good from the fortune she received at the shrine, and coincidentally runs into Yūto on the street. Her hairpin gets knocked off into the river and Yūto goes in to retrieve it; as a thank you gift, Shiina prepares some cooked squid, but hurts her foot in the process. Mai and Ryouko, two of Shiina's friends, and Yūto come to pay her a visit, during which Yūto gives the three girls an unforgettable massage, a "punishment" for losing a game of old maid. Later on, Yūto and the others leave for the day, but Yūto comes back because he was worried about Shiina. Yūto helps her by preparing dinner, and the two spend the rest of the night having fun together. On the day Shiina returns to school from the holidays, she is cheerful, and gets giddier with joy when she meets Yūto, even with Haruka near him.

Yuuto is devastated when Yayoi tells him to stay away from Haruka so she can focus on her audition. According to Yayoi, Haruka has agreed to make her debut as an idol. Haruka herself seems to be having fun and working hard at the lessons, so Yuuto kills his own feelings and distances himself for Haruka's sake. Milan, who knows Yayoi's true personality, notices that there's something strange going on with this whole situation. Then, Yuuto receives tickets to a live concert on the same day as the audition's finals, February 14th, from Milan.

Yuuto has been asked by Haruka to go out to an amusement park. Yuuto and Haruka, of course, are anxious and excited as they realize that it is a date. Then that day at the amusement park, they meet again with the professional celebrity manager, Kayahara Yayoi, who they met at their New Year's temple visit. Yayoi, who was at the park for work, asks the two for help. After enjoying a variety of rides, they leave to meet Yayoi. She had told them that she needed photos of the two of them, but the photo shoot ends up being mostly for Haruka. In actuality, Yayoi had other plans in mind...

Ordered by Mika, Yuuto goes to her all-girls middle school. Yuuto is taken by surprise when Mika's friends take him to her classroom and everyone greets him like an idol. Mika and her friends take Yuuto to the Modern Theater Arts and Culture Research Club room, and show him their love-fantasy girls play. However, while Mika was gone, her friends treat her by leaving her and Yuuto behind. It's already dark when Mika finishes cleaning the clubroom with Yuuto. When they try to go home, they are locked in and trapped in the clubroom.

Early in New Year's, Shiina sprains her foot. She hurt it while cooking for Yuuto, who, a day before, had found the hair clip that she dropped in the river. Sawamura and Abina comes to visit poor Shiina, but they bring Yuuto along as a surprise. After having a fun time together, everyone goes home, but Yuuto comes back, worried about Shiina. Yuuto makes dinner for Shiina, whose foot still hurts. It's quite a sweet moment, and Shiina, who is interested in Yuuto, takes pleasure in it.

It's New Years Eve. Haruka, who had promised to make a visit to the shrine with Yuuto and Shiina's group, hears about the early-day memories of Ouse-Misaki from Akiho. It is said that if you go to that cape with the person whom you want to be with, the two are guaranteed to be together. Akiho had been there with Gentou before, where they saw the first sunrise and exchanged a kiss. Haruka, hearing that story, hopes to go to that cape with Yuuto after their visit to the shrine...however, on their visit to the shrine, not only Shiina's group is there, but many of Haruka's underclassmen fans from school are there, and she is unable to find the chance to talk to Yuuto...

Yuuto is invited to the World's Maid and Butler Union's year-end party. Yuuto had been registered with the Union after he had worked as a butler at the Tennouji House. The event hall, Nogizaka House, is alive with maids and butlers. Hazuki and Nanami have to work as a party host, so Alice must escort Yuuto. Alice tries hard to be hospitable to Yuuto, but has a hard time doing so. Meanwhile, Yuuto wins the toy that Alice wanted during the bingo game, and gives it to her as a present. It makes Alice very happy, but...

It's Christmas Eve tonight. There is a little party at Yuuto's house, with Haruka and the Nogizaka family members. It's the first informal house party for Haruka, and she is very excited. Mika and the others have a great time as well. In the midst of the excitement, Yuuto faints from overworking. The Nogizaka's medic maid, Maria, comes to help, and tells Yuuto to stay in bed for the rest of the night. The party is over, but Haruka insists that she stays to take care of Yuuto. In the end, they end up spending the holy night by themselves...
