The casting comes after earlier reports linking Go Min Si to the project, sparking early excitement. However, the talks did not materialize, and the role ultimately went to Shin Si Ah. With a strong portfolio that includes The Witch: Part 2 and Resident Playbook, Shin is emerging as one of the most-watched young talents in the industry.

Grand Galaxy Hotel marks his first official project post-discharge, and fans are eagerly awaiting his comeback. He’s known for his emotionally layered performances in dramas like Sweet Home, 18 Again, and The Glory. Lee’s return with a high-concept fantasy drama has only amplified the buzz.
