Raina, the former After School member, posted several photos of herself in pink and blue bikinis on July 5 and 6 while relaxing by the pool.
The images highlighted her curvy figure and slim waistline, accompanied by captions such as “It’s okay even if it’s cloudy” and “I want to learn how to swim.”
Former groupmate Lee Jooyeon reacted with fire emojis, while fans praised the posts, with one calling for Raina to be named a national treasure.
Raina debuted with After School in 2009 and later found success in the unit Orange Caramel as well as a solo career.
