So it's Soonyoung that's been practicing too much that his shirt is thoroughly soaked with sweat. Saying out loud in front of the camera that he's taking out braces shows that he's got the attitude. He's the member that the trainees would like to introduce to their sisters and the member that the trainees most rely on. He thinks that it's important to make the happy virus to get the team together. He says it's quite a concern(as a joke) that MC Seungkwan is growing too quickly as an entertainer. He is trying his best to be what he wants to be.
