Exo M began to see the changes in their plump hyung ,he skips meals and exercises for hours at a time. They don't want him thin ,they want him squishy and huggable. That's where the Fattening Process comes in where they try to persuade Xiumin to go out and eat ,treat him to his favorite snacks 28 times a day ,but Xiumin just wouldn't give in to his own desire of fatty foods ,creamy cakes ,and steamed buns. Well that's what he thinks.
