Seri and Jungkook have been best friends for nearly ten years. For eight of them, Seri's been aware of Jungkook's massive, undying crush on her but she's never acted upon it--she's content with their friendship, content with knowing Jungkook will always still like her. 

But after a summer apart, Jungkook comes back to senior year with a girlfriend, which pulls Seri completely out of orbit and makes her realize perhaps she's liked him all along. With the help of her childhood friends, twins Taemi and Taehyung, Seri is determined to reclaim what was once her's--but not really.
