Sungyeol is alarmed when a high school classmate phones in to the radio show

On September 20, INFINITE sat down at SBS powerFM's 'Cultwo Show' where they listened to people phoning into the studio.

On this day, one person said, "Hey Sungyeol.  I'm your high school classmate, Nam Gyun. I didn't get very close to you at the time, but I remember when we skipped nighttime self-study to hang out.  I should have gotten much closer to you back then.  I regret [not doing that]."

Listening to this, an alarmed Sungyeol was unable to hide his surprise.  He explained, "I remember him now that I hear his name.  I had a dream at the time, so I remember shouting to my teacher, 'Teacher, I have a dream,' and then leaving the classroom," making everyone laugh.

Oh, Sungyeol, you rebel, you.
