[[ This Book is being re-written ]] Having an unfinished business with one of your best friends is not a pleasant thing. Especially if you two almost became more than 'that'. But just like how every story goes, something eventually went wrong and what's left are broken hearts, a broken relationship, and a broken trust. Halla, back after running away from all of that, decided to continue her life in a not-so-flamboyant way, just to fail miserably. But through that, she was able to meet a self-proclaimed ' charming-sunbaenim ' who's surprisingly willing to share her pain, and eventually his pain, as they bond over a simple glazed donut.
