Akaashi Keiji just turned 25 and moved in London, barely managing to communicate in proper english but determined to open his own bilingual bookshop/coffee shop. He managed to get a small apartment thanks to a family friend and is now adapting to the new environment. Every once in a while, through the window facing his in the fancy building across the street, he sees a beautiful young woman, either smoking a cigarette on her balcony reading a book or writing. However more than a few days a week, she disappears. Every Monday, she gets coffee at the coffee shop he’s currently working at to save money for his long-term project. At the coffee shop, the woman always gives the name Marie but he’s got a feeling it’s not her real name. In his imagination, she’s a romance novel writer, who used to be a spy. Somehow, he doesn’t have a clue of how famous the woman is. Y/n is a actually a songwriter. Although, Keiji’s not entirely wrong: she is writing a novel at the moment. One day, as he reads the papers while walking in his street, he finds an article about a world wide famous pop star dropping hints that she’s releasing a book. On the picture of the article, he sees her. The woman from the balcony. And then he sees her. Exiting a vintage SL Pagoda as if she was a nobody. The only hint? Sunglasses. And the woman next to her on a phone call who might be her manager.
