An eighteen-year-old female student, Sun Young, appeared on the show and talked about how she took over the role of her father as it got too hard for him to be active in finances after retiring. She revealed that it was hard for her to even study like she wants to because of her father who only drinks and never works.

After hearing this, Kyuhyun said, "I'm so upset that I'm unable to speak.  I thought about when I was young; my father ran a cram school, so I had to study like a Spartan with no choice in the matter.  I did not know of the happiness of Sun Young, who wants to study so much, and I just complained, saying I didn't want to, and thinking of that made me feel apologetic."

A lesson on gratitude!  Study hard if and when you can.
