"Saikai" lyrics

When I was young and lost
You showed up, and had my doors unlocked
Like threads, petals unfold
A red kawara-nadeshiko

You have shown me that I am still capable of caring for someone else
That I still bare the same innocence inside

Cause now I know that
Pain cannot define the past
We are built to overcome endless mishaps
You know, it is not so bad
When you are with me
Cherish as long as we last
Cause S is not for sayonara
Let memories play back

I knew I must step up
You deserve the world and more
The truth is that you'd rather
Spend our limited time together

Protection alone is not enough
Providing cannot fill an empty cup thirsting for love
I questioned myself a lot–

What do I know about love?
How can I recreate what I've never had?
All I know is that I must keep you thriving
If nutrients are what you lack
I will water you with every drop of blood I have

But now I know that
Sacrifice is the easy path
My absence cannot ever change the fact
I wanted the very best for you, believe me
Our threads in red can never be cut
And S is not for sayonara
Will you forgive me at last?
