February 27th-March 4th: After a bad start to the day breaking some plates, Yuno gets a low score on her grammar test and has to take a makeup exam. After studying for the retake, she gets a perfect score, but accidentally rips her sheet. On April 1, Yuno hears from the landlord that new freshmen will be coming to Hidamari Apartments, so the girls help clean the other rooms up. April 3rd: One of the freshmen's parents arrive with her things and offer to take the girls out to lunch. While they do that, the new freshmen, Nazuna and Nori, arrive at the apartments and are surprised that they cannot find anyone else. When the girls get back from their lunch, they meet with the new residents and officially welcome them to the apartments.

The girls hold a welcome party for Nazuna and Nori. Miyako brings a 'question dice' in order to find out things about the freshmen. The next morning, the gang are surprised to hear Nazuna is in general education instead of the arts department like they had assumed. Miyako thinks back to July 19th of the previous year when she accidentally set a small part of her hair on fire, and she and Yuno went to a hair salon named Olive run by twin hairdressers.

After the first day back at school, Yuno has trouble deciding what electives to take. After talking with Sae and Hiro, she decides on planes. Back on December 10th, Yuno runs into Sae at the bookstore, where they learn her the magazine which published her novella has already sold out. They later go to a café where Sae talks about whether she should aim for further teaching in literature or art.

Natsume gets a brief chance to walk home with Sae. Yuno, Miyako, Nori and Nazuna go to a home store to buy some new curtains for Nori's apartment, since her current ones are too short. Much to Nazuna's surprise, Nori goes with her suggestion. After running into the landlady at the gardening section, they buy a bunch of tomato seedlings to plant in the garden. Afterward, everyone has dinner at Hiro's place, and Nazuna and Nori start to bond.

The girls go in for their physical exams, and Yuno is not too pleased with her results, which say she has shrunk since last year. Yuno gets a wrong number call from Arisawa, a former senior, and thinks back to when she met her on January 31. Yuno had left her cell phone at school, which was found by Arisawa who was drawing in the classroom. She draws a picture of Yuno and gives her some advice about college and the two become friends.

On October 15th of the previous year, Yoshinoya appears to be down, and is constantly checking her cell phone, leading Yuno and the others to think she may be in love. It later turns out she has been reading a romance novel on her phone. April 26th: The girls spot Nazuna on numerous occasions being assisted by boys and wonder if she is popular among them. When asked about it, Nazuna says she is not too keen with it since it makes their other girls jealous.

Sae's younger sister Chika visits the Hidamari Apartments once again, where she meets Nazuna and Nori for the first time. The girls plan a picnic at a nearby lakeside park and later recount what they did and talked about back at the apartment building. As Chika is the same age as Nazuna and Nori, the three of them are able to quickly become friends.

Yuno and Miyako hear from Nori about a delicious crab fried rice dish that is on the school menu for a limited time and become determined to try it. Unfortunately, it is sold out by the time they get to the cafeteria the next day, so Hiro makes them the dish with imitation crab. On September 26 of the previous year, Yuno struggles with drawing a motif, and feels depressed about the result when her drawing is not scored very high.

On November 22nd, a few months before Yuno and Miyako would come to the Hidamari Apartments, Sae and Hiro's were in their first year and shared the Hidamari Apartments with their seniors, Misato and Riri. Sae has had trouble sleeping due to her writing work, so Hiro decides she will move into the room next to her's to support her. May 21st: Yuno and Miyako do some sketching at the park, where they throw stones at a weird shaped rock in the river.

After accidentally flushing her apartment key down the toilet, Yuno asks the landlady for another one. While the landlady tries to find the spare key among various other junk, Yuno spends each night sleeping over at each of the residents' apartments. After five nights, the landlady manages to find the spare key and Yuno finally returns to her apartment, only to be greeted by a foul smell from some leftover cooking.

On June 5th, it begins raining and will continue for the rest of the day. Yuno and Miyako see a puzzle involving matchsticks on TV where the answer is revealed to be online, so they head over to Nori's room to check it on her computer; Nazuna had already come over. After playing for a bit on the computer, they order a pizza around noon and later Hiro and Sae also come over for the same reason Yuno and Miyako had. Back on February 16, the seniors are participating in a tradition where they display voluntary final projects around the school. Yuno realizes that Hiro and Sae will be graduating the following year and that she and Miyako will soon become second-year students. On March 7th, Yuno and Miyako enjoys the cherry blossoms during the graduation ceremony.
