By an unexpected chance, Chinese girl Fu Rao got the opportunity to study in London. She was surrounded by a group of new classmates and friends. Her side is always filled with ambiguous love and desire, and flickering temptations and heartbeats. Until a flu swept through London that winter, subverting all love and hate. Fu Rao's psychological defense was as shattered as tarot cards. What's terrible is that she finally found out that she was deeply attracted to the foreign boy Louis Wei. His pure and charming smile saved her from the cold and gray real world, but at the same time made her fall into a new spiritual prison. All love, desire and sorrow are handed over to the flowing water of the Thames River, so that the most gorgeous memories and the most passionate youth will be treasured forever in the deep blue sea.
