On March 20, Byun Yo Han's label Saram Entertainment confirmed to news outlets, "It's true that Byun Yo Han will be leaving the cast of 'City of Stars'."

Previously, Byun Yo Han was cast as the male lead Yoo Dong Ha of 'City of Stars' - a drama dealing with two men who dream of flying to space. In the story, Yoo Dong Ha is a former airplane pilot who suffers from claustrophobia due to a certain accident. 

However, with Byun Yo Han's departure from the upcoming drama, the production will be seeking a new male lead. Set to be 100% pre-filmed, 'City of Stars' will air some time later this year.
