I don't know if this sounds weird or just plain fangirl, but my ABSOLUTE favorite part of 60 Seconds is 

when Sunggyu says "Lipseul~"

That part of the MV is like when I'm on cloud 9.

My favorite part of the lyrics and the MV.

In the MV, when he sings it, his lips move oh-so-well.

Here's the part. Right at the end, before the GIF starts over, He is saying "Lipseul"

His lips are amazing.
