My honest opinion? I love everything about this comeback (It's hard not to be biased but I'm swith!).

Anyways, their title song "bubble", their vocals, MV, choerography are so good. The “bubble, bubble, bubblе” are very addicting and stuck in my head. I truly enjoy listening to it. It is definitely an easy to listen.

The MV? The MV has a great production and it is so fun to watch. Everyone looked good, the set was amazing. 

So, what about you?
