+Kpop Lovie Yeah somewhere in the comments of that dance practice a commenter said she herself was a ballerina and Seungkwan's form was perfect every time he did the spins
He had to have taken ballet at some point in the past because he knows how to spot and is really good at it. His arms are beginner though so he probably wasn't in dance for very long.
Also, this isn't rlly related, but our Seokmin made a cover of it in Sukira - Kiss the Radio if ever you want to check that out. 😉 Note: He sang it in front of Ryeowook (idk da spelling) himself! 🙂
