A Warm Rainy Day In Tokyo by Kana Wu
Bella Bell lives a perfectly ordinary life with a perfectly ordinary office job in suburban California, where she longs to break free from her perfect sister's shadow. So when Little Bear Café chooses her to train its new franchisee in Tokyo for the summer, she jumps at the chance.
But even a dream come true can get complicated. From the moment she steps on the plane, she annoys her pompous, handsome seatmate, insults her apartment manager, and gets caught up in her new neighbors' drama. And everywhere she turns, she keeps running into the arrogant stranger from her flight—and she can't seem to get him out of her head.
Ryo Yamada is at the top of his game: a high-powered job, no shortage of potential girlfriends. But his life is turned upside down when his family asks him to return to Tokyo for good because of his sister's failing health. And now he finds himself avoiding his childhood friend whose feelings he doesn't return. And bumping into the irritating, pretty redhead from his flight—who may not be so bad after all. The last thing he expects is to fall in love.
As the new café opening and the end of Bella's time in Tokyo draw near, Bella and Ryo grow close—until they discover their circumstances may tear them apart. Can they find their way back to each other for good?
