See you later, Adachi! The Shimamura family's headed to the countryside to spend a few days with Grandma and Grandpa. But upon reuniting with an old four-legged friend, Shimamura comes face-to-face with her past—and her fears of a painful future yet to come.

It's spring, the cherry blossoms are in full bloom, and Adachi and Shimamura have been assigned to the same second-year class! Hooray! But now Shimamura's making new friends—so where does that leave Adachi? Can she overcome her shyness to get Shimamura back, or will she lose all the progress she's made? Perhaps a sleepover is in order!

Summer break is here, and Adachi's determined to spend it with Shimamura. Unfortunately, Shimarmura's old friend Tarumi has beaten her to the punch—as Adachi discovers when she catches the two of them together. Will this rude awakening give Adachi the push she needs to finally confess her feelings? And is Shimamura even ready to hear them if she does?

Adachi is skipping class when she first meets fellow truant Shimamura in the gym loft, and just like that, a friendship is born. Except now Adachi's having dreams about kissing her, and she doesn't know what that means, but she's pretty sure it's not something you do with a friend. What are these strange feelings she has when she thinks of Shimamura? And is it possible Shimamura feels the same way?

Christmas is here, and for the first time in her life, Adachi has someone she really wants to spend it with. Meanwhile, Shimamura agonizes over what to get Adachi as a present. They may not be standing under the mistletoe, but will a Christmas miracle bring them both what they're hoping for this year?

It's February 4th and Adachi has a question for Shimamura about Valentine's Day—if, that is, she can muster the courage to ask. A lot can happen in ten days!

Saeki Sayaka is no stranger to unrequited love. What she's not used to is having someone confess their feelings for her—until Edamoto Haru, an underclassman, does exactly that in Sayaka's second year of college. Haru is forward and unhesitating in her affections, the opposite of cautious, reserved Sayaka—but if she can find the courage to reach back, this time, she might find what she's been waiting for all along.
