[TOMT] Emo/Hardcore song, I can't find it!

I watched a music video years back of some kind of Emo/Post-hardcore band. They were lesser known (order of magnitude lower than All Time Low, or DGD, but somewhere in the middle sound-wise of those two bands.

The song in particular I know does have the standard verse-chorus repetition of normal pop songs but has a few more breakdown parts. The main thing sticking in my mind is one breakdown the singer screams three words, really punchy and punctuated in the beats. Something like “Just - one - break”, or “One - more - breathe”. The words escape me but it was something similar to that.

I remember vaguely the music video the singer has more of a clean cut hairdo in a bit of a combover but it’s really short hair. I recall them dressed in some kind of grade school-like uniform.

Can anyone help? I’ve been googling for over and hour and nothing comes up.
