Lee Jang Woo and Bora had a little fling in the jungle. 

On 'Laws of the Jungle in Panama', the team joked around as they drew on each others faces with ash. During this fun time, one of the members, Lee Jong Won, asked Bora, "Do you have a boyfriend?" And as soon as Bora responded no, he  said, "Would your mind be positive or negative if Lee Jang Woo wrote down his number on a note card for you?"

Bora simply said, "Wow", as she seemed very shy. Then Lee Jang Woo stood up and said, "Give me a note card", as if he was going to give her his number at the spot. The team laughed, and jokingly responded, "This is the first time seeing Lee Jang Woo smile that big ever since we got here." 

It seems like Lee Jang Woo might be serious about giving his number to Bora!
