This beautiful singer has been rumored of being forced to leave the reality program show Law of the Jungle after experiencing pain.

Reported by Soompi, unable to endure the pain, Chae-yeon eventually revealed the pain she felt to singer Hong Jin-young, after having had time to hide it. Chae-yeon cried as a result of the pain, so Kim Byung-man told her to lie down while waiting for the medical team to come. After being examined, the medical team said that the pain in her abdomen was caused by not eating for 70 hours. She was finally rushed to the staff’s lodging to get food and be treated. The 20-year-old singer claimed to feel disappointed because her body was unable to survive. “I started feeling small pain in the morning but I didn’t want to cause problems so I just held it back,” Chae-yeon said.
