15-sai, Kyou kara Dousei Hajimemasu.

When high school freshman Hiyori is suddenly left without a place to live, a surprising offer from her classmate, Kouki, turns her world upside down. He proposes they move in together, a proposition that sounds like the setup to every shoujo manga she’s ever read. What begins as an unconventional living arrangement between two seemingly ordinary teenagers quickly spirals into a delightful, if often awkward, cohabitation comedy. As Hiyori and Kouki navigate the uncharted waters of living under one roof, they soon discover that their carefully constructed boundaries are constantly being tested. With unexpected feelings beginning to blossom and the complexities of young love (and a few other interested parties) entering the picture, their everyday lives become a charming tangle of misunderstandings, budding romance, and the undeniable drama of growing up.
