OVA of Hoshizora e Kakaru Hashi to be released after the sixth volume of the Blu-ray of the TV series.

Hoshino comes back to his childhood place. He goes in pursuit of a monkey taking his brothers hat and meets Ui. He kisses Ui by accident by falling on her and Hinata appears and thought Hoshino forces himself on Ui calling him a pervert. When the brothers reach the Yorozuyo inn they are welcomed by the owner and shows them their room. When Hoshino came to bathe he was accidentaly seen naked by Tsumugi Todo and the owner of the inn Senka Yorozuyo. In the morning they go to the school they transferred in and Tsumugi shows the brothers the way to their schools. When Hoshino enters the class, Hinata notices him and she was surpirsed to see him in their school

Hoshino gets shown around the school, makes new friends and gets shown around the town. The title comes from Hoshino saying "That's why it tasted like cheese" (Referring to Ui's muffins that she had for lunch) when Ui bought lots of cheese treats from a shop, explaining that she likes cheese. Ui takes Hoshino's comment the wrong way, thinking he was talking about the kiss.

Following an awkward morning and breakfast with Senka, Kazuma and Ayumu head to school with Daigo. As Ui and Ibuki catch up, Kazuma experiences an aura that he is being watched. Class breaks for lunch; on his way with Daigo to get food, Kazuma experiences another aura as a girl hides. Homeroom is let out; as Kazuma leaves with Daigo, he spots the girl and gives chase. Bumping into and startling Madoka instead, bodyslams him onto the floor. The next morning, shooed out of the inn, Kazuma rethinks the incident and decides to apologize to Madoka; finding her at the shrine. Making up, she inquires about him and Ui, brought to tears upon hearing they kissed. Watching this from atop a tree and upset at Madoka crying, the girl from earlier reveals herself to be Koyori Toudou, Tsumugi's other sister. Berating the poor boy with acorns, and to the defense of Madoka, Koyori pardons Kazuma and leaves. On their way from school the next day, Ui and Kazuma bump into Ayumu. With a moderate fever, Kazuma piggybacks him the rest of the way as Ui fantasizes about being carried. Back at the house, Ayumu asleep, Kazuma and Ui relax in his room. Senka drops by with Tea and Daifuku, of which Ui immediately begins to make a mess of herself eating. To his amusement, Kazuma laughs.
