Doushite kimi wo suki ni natte shimattan darou
Donna ni toki ga nagarete mo kimi wa zutto
Koko ni iru to omotteta noni
Demo kimi ga eranda no wa chigau michi

Doushite kimi ni nani mo tsutaerarenakattan darou
Mainichi maiban tsunotteku omoi
Afuredasu kotoba
Wakatteta noni
Mou todokanai

Hajimete deatta sono hi kara
Kimi wo shitteita ki ga shittanda
Amari ni shizen ni tokekonde shimatta futari

Doko ni iku nori mo isshou de kimi ga iru koto ga touzen de
Bokura wa futari de otonaninatte kita
Demo kimi ga eranda no wa chigau michi

Doushite kimi wo suki ni natte shimattan darou
Donna ni toki ga nagarete mo kimi wa zutto
Koko ni iru to omotteta noni
Mou kawanai

Tokubetsuna imi wo motsu kyou wo
Shiawase kao de tatsu kyou wo
Kireina sugata de kami sama ni negatteru kimi wo

Boku janai hito no tonari de
Shukufukusareteru sugata wo
Boku wa douyatte mioreba ii no darou

Doushite kimi ga suki ni natte shimattan darou
Ano koro no bokura no koto
Mou kawanai (kangaeta kangaeta)

Doushite kimi no te wo tsukami ubaenakattan darou
Donna ni toki ga nagarete mo kimi wa zutto
Boku no yoko ni iru hazu datta (sono mama ni)

Soredemo kimi ga boku no soba hanareteite mo
Eien ni kimi ga shiawase de iru koto
Tada negatteru
Tatoe sore ga donna ni sabishikute mo (sabishikute mo)

Translation:

Why did I end up falling for you?
No matter how much time has passed
I still thought you were right here
But you've already chosen a different path

Why couldn't I call out to you at all?
Every day and night growing emotions
And words overflow
But I realized that
They'd never reach you again

Since that day I first met you
I felt like I already knew you
You and I melded into each other so smoothly

It was natural for me to be where you were
The two of us grew up together
But you've already chosen a different path

Why did I end up falling for you?
No matter how much time has passed
I still thought you were right here
Now we can't turn back

The special meaning held by this day
Today you stood with a happy expression
You looked beautiful while praying to god

But I wasn't the one next to you
And the image of you receiving blessings
Of that how could I let go?

Why did I end up falling for you?
How we were before
We can't return to it anymore (I've thought it through, thought it through)

Why didn't I hold on to your hand?
No matter how much time has passed
You should've always been by my side (never changing)

But still, even if I'm nowhere near you anymore
I'm praying that you
May be happy for eternity
No matter how much that would make me lonely
