It's Yuno and Miyako's last summer as high school students! They want to make the most of it, but summer also means preparing for college entrance exams. As the impending tests weigh on their minds, the lighthearted and unchanging everyday of Hidamari Apartments and school life unfold.
All good things must come to an end, and with Sae and Hiro's graduation, the two girls bid farewell to Hidamari Apartments. But they aren't the only ones who have to face the future head-on. Yuno, now in her third year, is struggling with career uncertainty herself! And when a new first-year, Matsuri, moves into the building and old friends make way for the new, how will timid Yuno handle her new role as senpai?!
Yuno is thinking so hard about her future prospects, it's even haunting her dreams! But the cure for a furrowed brow is good friends, and the girls at Hidamari Apartments (including their newest tenant Matsuri!) aren't about to let Yuno stress out alone. Whether it's an unexpected encounter on a college visit, a swimsuit shopping adventure, or a school trip to Kyoto, Nara, and Osaka, the days are getting a little more out of the ordinary...and a lot more fun!
With Sae and Hiro staring their college entrance exams straight in the face, the underclassmen of Hidamari Apartments are reminded that their own graduation is just a short time away...but there's still plenty of time for the girls to make fun memories in the meanwhile!
