Rain revealed he suffers from claustrophobia.

In his latest video on his YouTube channel Season B Season, Rain shared his activities in Mongolia, Taiwan, and Hong Kong. During his free time before a performance, the singer-actor was waiting for a helicopter to take him to the Mongolian steppes.

He confessed, "I have a bit of claustrophobia, so I'm not sure if I'll be okay." When suggested to sit in the front, Rain hesitated but got into the front seat. He continued to worry, saying, "I wonder if it'll be okay. I had a scene in a movie where I had to get into a coffin, and since then, I get claustrophobic when I'm confined to a small space. It's like a shock."

Once the helicopter took off, Rain said, "It felt like I was filming a movie. I could see the scenery, and I started to feel more comfortable. It made me realize you have to ride expensive things. This helicopter is great."
