K.Will might be a lean singing prodigy now, but he revealed that his parents were once scared that he might become obese.

On the May 9th broadcast of SBS' 'Star Couple Show', K.Will shared, "My mother told me that when I was a baby, I didn't sleep at night and kept crying. She hoped that I might fall asleep in a quiet and silent place, so she once put me into the wardrobe."

"I am an only child, and I was on the chubby side during elementary school. My parents worried that I might become obese. Only children usually get treated with special care, but my mother was definitely not like that. My parents were a weekend couple, so I was only able to eat side dishes with meat when my father came home. I normally ate only vegetables."

"On the days my father would come, I tried to grab the meat, so my mother blocked me with her chopsticks. I once cried and went to my room because of it. I talk to my mother about it sometimes and said, 'If I ate a lot, I would've grown taller.' My mom replied, 'You were also my first child, so how would I have known? If I had another child, I would've raised it well, but we failed with you'," bringing laughter with his mother's brutal honesty.
