BoA was cute and did a great job in the Crazier live clip, right?

To celebrate the 25th anniversary, they showed various things for the fans.

This live clip also showed BoA's live performance roaming around the office building in a one-take style.

It was really, really cute.

They are professionals when singing, but seeing their lovely sides here and there made me feel like I was killing two birds with one stone.
