Joy preparing to become a dog groomer on 'I Live Alone' was incredibly realistic.

I went to learn the practical training with a pounding heart, but it's not easy.

I returned home completely exhausted after a tough struggle, but to get the certification, I also have to prepare for the written exam.

Joy, who candidly says it's been a long time since she stopped studying haha...

It was really funny to see the realistic side of someone who really needs to study but keeps putting it off lol
