The idol star couple continued their vacation in Hainan, China and decided to dress up for the occasion. Both Sungjae and Joy dressed in traditional Chinese clothing, and the Red Velvet member in particular caught everyone off-guard with her slightly revealing dress.

Sungjae commented surprised, "She's like a baby, but when she's sexy, she can be sexy despite her age."�He continued, "I don't know where to look. I wish that she would cover up."�

He seemed to get over his shock, however, as he ended up taking a few photos of Joy in the outfit.�
