Of all the sudden
greetings and goodbyes,
the numerical formula for it can't be read
I'm looking for it, I'm really looking for it.
I placed my pen down
and sighed out in disappointment

Nobody knows
Nobody has found it yet
Nobody has found that elusive formula
But I have found it
I did find it my damn self!
But it's a secret kept for only my benefit

Ah, ahhh
Never again will I have to listen to such incessant babbling
Ah, ahh
I never want to experience a farewell or any parting like that twice

*Chorus
Fortuity, fortuity
it's how we arrive here in the present
What's going on? What's going on?
I was there with you, I was there with you
Fortuity, fortuity
it's how we arrive here in the present
Are you happy now? Are you happy now?
I wonder if you're still laughing today?

That formula that everybody dreams of,
it's very existence is detestable, you know
You observed silently
You looked at it and then laughed
I joined in with a pained smile
and curse my foolish equations

Of all the sudden
greetings and goodbyes,
the numerical formula for it shouldn't be read
I threw it away.
It's crumpled up in the trash can
All is fair in love and war until you're on the losing end

Ah, ahh
Never again will I have to listen to such incessant babbling
Ah, ahh
I never want to experience such heartbreaking coincidences again

*Chorus pt. 2
Fortuity, fortuity
I am the product of eventuality
Right here, right now
I am breathing. I am living.
Fortuity, fortuity
I am the product of eventuality
Right here, right now
I can't stop crying, I can't stop crying!
Ah, ahh

Adios, luz de mis ojos. . . (Goodbye, the light of my eyes/light of my life)
Mata ashita. 「また明日。」 (See you again tomorrow)
Which one of these is the real one?
(Do) You see the difference?
Even now my once self centered and ambivalent heart, sees no distinction
It feels like I'll really break down
Ah~

*Chorus pt. 3
Fortuity, fortuity
it's how we arrive here in the present
What's going on? What's going on?
I was there with you, I was there with you
Fortuity, fortuity
I am the product of eventuality
Right here, right now
Are you angry? Are you crying?

“Goodbye”s along with sweet “Good morning”s
paired with “I'm sorry”
In addition to the massive teardrops I cried back then,
your hand had my back and my warmth was transferred

Now, when we add it, we will subtract it,
divide into pairs, multiply them jointly
Multiply again, then divide them up, bring it together
Love's formula is now solved!
