Girl group Melody Day's member Yein went on a drastic diet.

Recently, one online community forum posted before and after photos of Melody Day's Yein after her 15kg weight loss.

In the picture, she is chubby and cute in the before pictures but upgrades her beauty as she loses weight and matures in her looks.

"Our members are all really skinny but I was like a rubber band. It was a more realistic body," said Yein recently during a talk show.

"When I was at my peak, I was 62kg. But I lost down to 47kg within 3 months now," said Yein.
