English Translation:
Happy synthesizer I'll play a melody
That will almost reach the inside your chest

Scattered faint one-sided love
It's a funny story, now that I think about
Everything seemed to shine so brightly
Those days are smiling clearly

Do I have to remember only holding back?
"Would you [bad word] an adult? you don't have to do that
I didn't know anything, but I couldn't say I didn't know
"It suits you very well" I'm sorry I lied

Happy synthesizer I'll play a melody
That will almost reach inside your chest
Boring "obligation" or all the things you hate
I'll erase them with this sound

There's one small thing
That this useless me can do
Plain words that can make your heart beat
I'll deliver them to you through electronic sounds

Liking someone is not an excuse
We don't need "stubbornness", right?
If you blame it on the era and give up, that's the end
If you don't step forward, nothing starts

"Sorry, it's so late... You were sleeping, right?"
"I'm surprised! I was going to call too"
Like it's about to touch the heart's backside
The happy sound of two attracted people 

Happy synthesizer look, things will get better
I'll play a inspirational melody
You don't have to pretend to be strong, okay?
Just be [bad word] to yourself

There's one small thing
That this useless me can do
little shy but a simple mind
I'll deliver it to you through electronic sounds

Happy synthesizer I'll play a melody
That will almost reach the inside your chest
Boring "obligation" or all the things you hate
I'll erase them with this sound

There's one small thing
That this useless me can do
Plain words that can make your heart beat
I'll deliver them to you through electronic sounds

Happy synthesizer look, things will get better
