[bad word] (and translation):
僕が君を想う歌
The song for which I think of you
僕が君に伝える歌
The song for which I tell you
再び出会うその日まで
Till the day of meeting up again
「またね」
"See you"

Translation lyrics: (Romaji is next)

You started walking, turning your back on me
without any exchanged words
My mind is wavering, and I cried out like a child
Don't go Don't go Say

I started walking, turning my back on you
I have to go before my tears drop
Pretending I dislike being too happy,
I tried to act strong, and let go of my ideal future
I can't get back my wish

My small one-room which I feel a little roomy
Seems to widening a crack of my mind
For a momentary minute or second which I feel a little long,

I want to stay with you

The world doesn't allow me even to wish it, I wonder
Even only one lie I told
Will go and lead to your tears
I've ever repeated sin so much how I can't count
One is what touched your hand
One is what tried to live gently next to you

In finite memory and time
Like what let off one of the past whenever picking up one of the today
The existence of me that only had settled there
From your memory, it must be erased

Can we never turn back again?
Is this the beginning? Or the end?

The night I'm sleeping on a large bed isn't still over
I'm gonna dream alone again
That's a dream to trace your memory
I've ever repeated sin so much how I can't count
One is what touched your hand
One is what tried to live gently next to you

I'll atone by a pain of the loneliness,
So let me stay gently in your memory

I wish we meet up again in a former mind
Then let's go hand in hand
Till it's that time,
"See you"

Notes:
from Y to Y = "from to Z." Or the words that is written on rings, is original author's sad memory.
Y = His initial or somebody's initial who he had loved. They are the same by coincidence.
one-room = room in one-room apartment. And, original author's name is "OneRoom" ("...P" is the another one in Niconico).
