Dear Hyeri

Joo Eun-ho is an unknown announcer with 14 years of experience. She struggles to get the chance to have her name recognized by the public. She also has another personality, Joo Hae-ri, due to a deep wound in her heart. Her alter-ego, Joo Hae-ri, is super positive and works as a parking attendant.

Jung Hyeon-o is Joo Eun-ho's ex-boyfriend; they dated for a long time but broke up. He became a star announcer as soon as he joined the broadcasting station and is the most-liked announcer by the public, but Jung Hyeon-o also carries a hidden wound in his mind that he has never shown to anyone. Somehow, Joo Eun-ho and Jung Hyeon-o reunite and help cure each other's wounds.
