If I would be in your position dear reader who can't read the second b-side lyric 'のぼせ上がたい' for NOW.
_{(you already know about 'BREAKDOWN-SHOWDOWN' the other b-side. If not, you can find it here. There you also can find a short interpretation of the lyric itself in the "author's comment" area.)}

But I'm here to tell you a little bit about 'のぼせ上がたい'~

Well... First: 'のぼせ上がたい' is written in romaji 'nobose agatai' and means as much as "I want to go mad".
It's about ugly side of society which is often hidden in the dark!
Yeah...
Damn... I should really make a script before posting something here...
It's hard to explain impromptu... but let me try:

Society is one of the parts which forms a human being in psychological ways. People you hang out with, your parents, short: Every person you somehow have contact with can influence your mind in some way, I guess.
It could have positive effects on you but it could also have negative ones.
Not only is society influencing your behaviour, it also is trying to control you.
And I guess that's the point where the lyric comes into play.
What if you don't want to give away the control? But society is trying to take it form you by force or whatever.
I think that's the point when people think you're slowly going mad or something.

Here the lyrical narrator of the lyric is talking about a way out of misery which he/she is trying to find.

I guess that is what 'のぼせ上がたい' is about.

I hope you're now even more curious to read the new lyric!
I'll come back with other/more information sooner or later!

Be well prepared and stay tuned!
