Himawari House by Harmony Becker
When Nao returns to Tokyo to reconnect with her Japanese heritage, she books a yearlong stay at the Himawari sharehouse. There she meets Hyejung and Tina, two other girls who came to Japan to freely forge their own paths. The trio live together, share meals, and even attend the same Japanese-language school, which results in them becoming fast friends. But will they be able to hold one another up as life tests them with new loves, old heartbreaks, and the everyday challenges of being fish out of water?-goodreads
