おとななじみ

Kaori Kagaya and Haru Aoyama have been childhood friends since their days in kindergarten, growing up next door to each other with their families sharing a close bond. Now, at 24, they find themselves living in adjacent apartments, but their relationship is anything but straightforward. Kaori harbors deep feelings for Haru, yet he sees her more like a caregiver than a potential partner, often calling her "Mom." As they navigate the complexities of adult life, work, and unrequited love, other characters, including another childhood friend, Iori, enter the mix, stirring the pot of their stagnant romance.
