Yurim Lee, a stunning young woman, has a peculiar gift; she can sense when people have dishonest intentions. This becomes evident to her when their face is obscured by a dark cloud. The more dense the cloud, the more dangerous their motives. Unfortunately, this ability has caused more harm than good, resulting in her ostracizing from society when she was young. Currently, attending college, Yurim is a solitary creature who finds it challenging to place her faith in others.
While strolling home one day, a man emanating a dark aura attacks Yurim. Fortunately, Jooeun Lim, a stranger with hair resembling cherry blossom, rescues her. This brief intersection slightly illumines Yurim's lonely life, and they build a friendship. With Jooeun's assistance, Yurim learns to manage her extraordinary talent and starts to interact with unfamiliar faces. However, in her pursuit to regain her trust in society, she must confront a past she presumed to have forgotten.
