Red Velvet's Joy said that she'd die without BTOB's Sungjae on the January 9 installment of 'We Got Married'.

The two idol stars were enjoying a lovely vacation in Hainan, an island province of China. They rode a bicycle cart, a cable car, and even crossed a 1477 foot (450m) high bridge. Though Sungjae crossed it easily, Joy was definitely a lot more hesitant and afraid.

She said during her interview, "In that moment, I felt like I would've died if I didn't have oppa with me." Sungjae also commented, "Joy usually doesn't get scared, but when she does, it's at weird moments."
