Of the two virtuosic pianists, they are opposites of the same coin: driven, gifted, hard-working, but one unafraid and in need to love, the other deprived and avoidant of it. Byun Baekhyun, the former, encounters Seo Jooeun, the latter, and their story is nothing more than what it is: no grey areas, no ambiguity—just art. And it is, indeed, beautiful. 

Baekhyun loved Iseul, and she clearly saw that. But he's been going home later, the other side of her bed becoming colder and colder without his warm and comforting whispers and sweet promises. And just as coffee is capable of awakening, the disease that's been ridding through her body finally awakens, leaving her to leave him.
