Bomi doesn't know exactly why Byun Baekhyun, her new shift partner, hates her so much. First, they didn't attend to the same school. Two, and it was their first meeting when her boss told her that she's going to be Baekhyun's partner for two months. - which probably feels like hell for Bomi since Baekhyun hates her and probably wanted to retire from his job as a barista, if he could, but then he realized he doesn't have a lot of money if he wants to retire from this job. — she's not her, he always thought everytime Bomi walked passed him with a hot black coffee on her hand. she's just someone who reminds you about her, the devil whispered.

although it may be different now, the beginning is the same.
