Even though they performed Empty the last time they were on Sketchbook it feels different this time. Like...they don't feel like rookies anymore and it's very evident when you compare their recent performance to the first one. Also, they're not wearing their grandpa clothes anymore (even though they rocked that look too)!!!
I love this song. They sound and look so good. Seunghoon, stop trying to fight Mino for his spot as my bias. KSY's voice though!!!
