Premieres January 4th, 2025. The new PV is here. Check out the Crunchyroll article for additional information. Synopsis from AniList:
I, Teruaki Nakamura, transferred to a school in Okinawa and developed a crush on a girl named Kiyan-san, but I don’t understand her dialect. Higa-san is always helping me by translating the dialect. A slightly different cultural love starts on the southern island.
Indeed. Another one that popped in my head was Horimiya.
