My Darling Next Door Vol. 4 (Kodansha, 2022)

Just when Ririka works up the nerve to tell Hinocchi how she feels about him, he turns her down. Heartbroken and in shock, Ririka embarks on her school trip to Hokkaido… In a crazy turn of events, she runs into Hinocchi, who's there on a business trip. As they look at out at the nighttime view of the city, they're able to talk frankly about their feelings. Upon returning, Ririka finds that both Hinocchi's birthday and Christmas are quickly closing in… along with the distance between her and Hinocchi!
