“I have dropped 10 kilograms. There is a way, which is not to leave the house. You cannot meet with friends because they will definitely invite to eat or drink, ‘Want to go to a cafe? Do you want to watch or not?’ I will stay at home for a strict diet,” said Moonbyul.

Not only that, but Moonbyul’s diet also includes maintaining her food intake. She revealed that she only ate sweet potatoes throughout the day. “In the morning, I eat two sweet potatoes with one glass of milk.
