Synopsis[]

Mok Sol Hee is a young woman with an extraordinary and supernatural ability: she is able to “hear” other people’s lies, no matter how hard they try to obfuscate the truth. But this superpower has left her jaded: She no longer has any faith in other people, and now considers them all to be morally bankrupt. But that all changes when she meets a successful music producer named Kim Do Ha.

Kim Do Ha has become embroiled in a murder case, and has gone into hiding... in the residence next door to Mok Sol Hee. The producer’s closest friend Jo Deuk Chan, the head of the talent agency J Entertainment, is the only person who knows Kim Do Ha’s secret.

The next day, she meets Do-ha on the bus but does not remember him and helps him ward off a man that claimed he was cheating on her girlfriend. Do-ha is surprised that she believed him he did not cheat and Sol-hee tells him that she can hear lies. Then, five years later, Sol-hee solves another case and now has its own café where she meets her clients, as well as a coworker Cassandra and a bodyguard Baek Chi-hoon. Do-ha is now a famous music writer constantly wearing a mask that only his closest co-workers have seen in person, including Sha On, who brings him the award he won. A reporter manages to take a picture of him and find his home, forcing him to move to another apartment. Coincidentally, there is another man wearing a black mask in the new neighbourhood harassing women at night.
