He injured his ankle and had to undergo surgery

During a chat amongst the final four contestants, Amotti shared that he was once involved in a car accident and had surgery on his ankle. “I thought I might never walk again,” he admitted then. In a separate interview with TV Guide, he disclosed that the accident happened in Jan 2021. He was on the way to the gym on a scooter when a car door opened and hit his ankle, crushing his bone. “At that time, the doctor had told me that I may not be able to walk, let alone work out. It was devastating, but I had to overcome it,” he said.

The pair work out together, and Amotti mentions that Sung-bin shared some advice with him. “I did chat with Sung-bin about this and he told me that the shooting period would be quite long.
