As soon as the second demo song came out, all the members noticed.

It's a song made by Ha Sung-woon, but it seems like he intentionally didn't include English lyrics.

Since the members were praising him so much, Seongwoon's mouth curved all the way to his ears.

When Yoon Ji-sung teased him, Seong-woon acted like he was meeting them for the first time and shyly said it must have been written by someone who isn't good at English, and it was super cute.
