She does her best to hold it together and continue performing.

She explained to fans that she has an intense fear of heights.

Despite this, she is aware the platform is safe.

Fans commend her professionalism even during a scary situation!

A girl who doesn’t lower the lift even though she has a fear of heights… all for NSWER.
