They're lesbians Harold.
In all seriousness, this series is great. The author is even involved in an organization in Japan agitating for marriage rights for all, and promoted it unabashedly in the book.
The basic premise is two lesbians who haven't realized it yet fall im love over their shared love of food. And also there's trauma, well handled -- new characters in volume 3 include a loud and out asexual lesbian and a young woman suffering from trauma related to eating disorders. The chapters that hit heavy begin with trigger warning in fact.
