Shin Si Ah has officially replaced Go Min Si as the female lead in the upcoming drama Grand Galaxy Hotel. The casting change came after Go Min Si faced serious school bullying allegations. The drama, written by the Hong Sisters and starring Lee Do Hyun, is a sequel to the hit series Hotel Del Luna.
Production was delayed by three months due to the recasting. Shin Si Ah, known for Resident Playbook and The Witch: Part 2, will now play the lead opposite Lee Do Hyun.
Why Was Go Min Si Replaced?
Go Min Si was originally cast as the female lead in Grand Galaxy Hotel. However, in May 2025, an anonymous online post accused her of school bullying and money extortion during her middle school years. The post claimed she and her friends targeted disabled students.
Her agency, Mystic Story, denied the allegations. However, the controversy led to public backlash. Many fans demanded her removal from projects. The production team initially stood by her but later decided to replace her to avoid further issues.
“Given that the school bullying issue has not been fully resolved, we decided it was best to address this matter first. After discussions with the production team, we agreed on her departure,” Mystic Story told TenAsia.
Shin Si Ah Steps In as the New Lead
Shin Si Ah was quickly chosen as Go Min Si’s replacement. She gained fame through Resident Playbook and The Witch: Part 2. Her agency, Management SOOP, confirmed her casting on June 26, 2025.
Fans welcomed the news, expressing excitement about her pairing with Lee Do Hyun.
“Im excited to see their chemistry here! 🥹🥹🥹🥹🥹,” one fan wrote on social media.
“Omg!!!!!! Let’s gooo!!!! Main lead era for Sia and Dohyun is coming back🥺,” another fan commented.
