Shame is what Seokjin had when he looked at Namjoon's body as he rapped on stage. 

Shame is what Seokjin felt when he got off on Taehyung's deep voice. 

Shame is ran across Seokjin's mind when he watched Jimin show off his aegyo. 

Shame is the feeling he had when Yoongi asked him to sing a line instead of Jungkook. 

Shame is the way he was when Hoseok gave him a back hug and he liked it a little too much. 

But he didn't have any shame as he kissed Jungkook, loving the way their lips came together.
