Jackson declines Hani's invitation to sleep together, why?

On the recent episode of "Laws of the Jungle in Nicaragua", seems like the new idol members are now very comfortable with each other especially Hani.

While preparing to sleep, Jackson passes by Hani, who is sleeping warmly and comfortably in a tent, (thanks to the consideration of her oppas), and she boldly and jokingly asks him, "Since I'm alone, shall we sleep together?"

Jackson seems a bit flustered to Hani's mischievous question but replies, "No." When Hani asks if he's shy, Jackson wittily answers, "because "sleeping together" would definitely be the top searched keyword in portal sites," and made them both laugh.

Well, Jackson isn't wrong after all 'coz it's trending on Nate. (Haha!)
