Teen Top 30 Day challenge Day 20: Favourite performance by TEEN TOP

All of their stages are incredibly good and energetic, and I honestly can't decide on this one. 
But there's one which I highly recommend.
Those of you who sees the title and knows exactly which song I'm talking about,
can someone please tell me whether it is about a first kiss or something more? ;D *shot*
It's an L.Joe fancam... xD 
I deeply aologize if I made you hyperventilate or something just by the gif. 

First Kiss
