Side effect in English

Side effect
Lyrics: Mashiro
Music: Rei
Arranges: HIMEYURI

I chose this way for you.
Therefore I'm not bad.
Please don't blame me.
I'm not bad. I'm not bad. I'm not bad.
It's side effect.
I hard why.*

By my senses, I can slighly see,
Terrified of the shadows.
It's side effect.
Everything is destroyed
Like this.
If I'd wanted to be free,
I hard why.*

Before disappearing, we would be enchanted,
It can't be avoided,
It's side effect.
Everything is destroyed
Like this,
Going towards that place...
I hard why.*

I chose this way for you.
Therefore I'm not bad.
Please don't blame me.
I'm not bad. I'm not bad. I'm not bad.
It's side effect.
I hard why.*

*Literal transcrypt.
Maybe they wanted to say "I had a why" or a bad translation of "Muzukashii riyuu" wich, in that case, means "It's a hard why (reasson)" that would be "A hard why". Choose your favorite!
