Just wanted to leave something for anyone who was curious. These dialog options were found by opening the sharedassets0.assets file in a hex editor.

You may notice there are duplicates - I'm not sure if they are considered separate dialogue options or not. My guess is that they are, as these are almost definitely just translations from the original dialogue options, and so two phrases in the original language translate to essentially the same phrase in English.

Every time we do not know any thing any more, every time!
I chase the image of your body lost in the darkness of the sea.
I look at you.
More.
I love you.
I love you like it is not possible to love.
I see. I am mad from seeing.
I see you.
You touch the body.
I had seen you that morning on the beach.
Yes, that's it.
I am looking.
I am looking.
Don't look, look at me.
No.
Yes.
Are we alone?
I don't know.
I have trouble removing myself from you.
I have come.
Did you know I would come?
The sea.
Come close to me.
I do not know the word for saying that.
You have returned!
I desire you a lot.
Yes. You too.
Nothing else will happen in my life but this love for you.
Since the moment you looked at me I have desired you.
Sometimes I believe that to love is to see. To see you.
I want.
What an extraordinary coincidence.
I would like.
I wish to stay with you.
I think a lot about you since I have seen you again.
You have gone to the seaside.
It's impossible, I have to see you, it's impossible.
I know.
I cannot, I must see you every day.
Ah I love you so. What will we do?
I have seen you often.
How odd, I have no desire to return.
It would have been impossible for me not to come.
I too have returned for the same reason as you.
The smell of the magnolias is so strong, if you knew.
This spring is exceptionally nice.
The moon was nearly full last night.
Talk to me some more. Soon, I will not ask you anything any more.
Anything could happen!
Tomorrow.
It's nearly summer. Come.
Now, talk to me.
The weather is nice.
Such weather.
I look at you.
I love you.
I love you.
I know it.
Tell me more.
I am only certain that I love.
I hear you.
Our love.
Yes, that's it.
More. Talk.
I know nothing any more before today.
That's it.
You believe.
No.
Yes.
It is true.
I don't know.
Do not understand anything.
I understand.
I was not mistaken.
I hear your heart.
Come close to me.
Love.
What has happened to us.
I adore you, nothing can be done about that even with the suffering.
In all my life it is you whom I will have loved.
To live love like despair.
We watch the summer that is sleeping.
I loved you with a frightening love.
I do not know what it is.
Let's be quiet for a moment.
I do not understand what is happening.
I start breathing again.
My happiness is there.
For me.
I know.
It is the first time that you are mistaken.
Do you like it?
If you wish, we can stay the night here.
My love. My love.
That's it, yes.
It is good.
Talk to me.
Ah, my love.
I knew it.
I have always known, always!
Make something up.
The breeze always returns.
Tell me more. You can tell me anything.
Continue.
I would not have believed that it happened so quickly.
You are my love.
I love you. Fear nothing.
How nice it is.
I thought I knew everything. Everything.
I haven't lied.
You're making things up.
I am going to scream. I am screaming.
I will die.
I'm talking to you. I was talking to you.
We are silent.
No.
Yes.
There is nothing any more.
There is noise.
It is true.
I don't know.
Who are you?
I knew you.
I had forgotten you.
Do you understand?
I'm not certain that I wanted it.
I am not sure that I know you.
I am frightened, come.
What is it?
It is true. You are nothing.
What?
Nothing. Never. Nothing.
I'm boring you.
I don't see anything any more.
I see.
You have forgotten me.
I would prefer you did not love me.
It is when you sleep at night that I leave you.
It is not possible otherwise.
We cannot do otherwise.
It's complicated.
Those are words that frighten.
You know it. What I said there, you know it.
No, I know nothing.
I have forgotten the words for telling you.
I would also like.
I do not love you when I am silent in a certain fashion.
Be silent.
You should not tell me everything.
I feel good without you ever since I've known you.
But. No.
I am a little frightened.
I want to be with you, but how I want it.
I have said nothing.
I know nothing.
Ah, let me.
You are alone.
I do not know a thing, like you. Not a thing.
I remember.
I do not know. Like you.
We can always sing.
I am quiet.
I thought I had foreseen everything! everything! and then, see!
Your body will be taken far from me, and I will die of that.
Help me, I beg of you.
You are lying.
Look at me! I am screaming!
I love you.
Stop.
I cannot.
Stop talking.
The light is changing.
Something will happen, it is not possible.
No.
Yes.
It is true.
I don't know.
I am crying?
What are you crying for?
I am in the process of dying.
What is the difference?
Never?
Let us leave from here.
What are you crying about?
I do not know any more.
What is it?
Tell me to sleep.
What do you want?
You're talking nonsense!
It is not true.
Sometimes, when we talk together, it is as difficult as dying.
When I'm writing, I do not love you any more.
I do not love you any more. It is you who loves me. You do not know it.
As usual I have cried.
I sincerely believe that I could have not loved you.
I beg you, I implore you: do not do it!
I do not want to.
I have never longed more for the day when nothing will happen.
Be silent.
Liar, liar.
I cannot either.
Sometimes during the day, I end up imagining myself without you.
You should not tell me everything.
Oh how you cause me pain.
I have to go maybe, now.
Maybe you will not return any more.
I don't think it matters.
I have to go.
I cannot continue.
If we would not drink as much, this would not be possible?
I wish you would leave.
Why are you crying?
Let us choose to talk or say nothing.
It is impossible.
It's difficult.
The air is burning.
Pain, no, that is never possible.
It will be the same sky.
What will be left for me to see if you are not there any more?
I am screaming with you.
I think I remember.
Scream.
Die.
No. I am silent.
Do not come any more it is not worth the trouble.
No.
Yes.
It is true.
I don't know.
I need to sleep or I will die.
Once in a while it is calm here.
We hear nothing.
I will not come back any more.
Never.
I have forgotten.
I do not know any more.
I remember too.
I need to sleep.
Sleep.
I do not know anything any more.
I regret.
You do not speak any more.
I have started to suffer from the separation from you.
Never will I forget you.
Before you I knew nothing of suffering!
It is the pain that I love. I do not love you any more.
I do not love you.
For suffering from you.
We will forget.
It is over.
It is over.
It is of you that I am frightened.
I will cure myself from the lie of a love that is ending.
Be silent.
You have come too late.
Nobody knew.
Never have you screamed. Never.
It's over, I believe.
I can be silent.
It will start over.
I am frightened.
It is impossible.
I wish you were dead.
It is done.
Maybe I will not manage.
I'm coming back.
It is hell.
I will always love you.
Never will we know.
What could we do?
A glass of wine.
I would like a glass of wine.
I would like another glass of wine.
I want you to have another glass of wine.
I would like to drink a little wine.
I want some wine. I always want some!
Wine is so good.
Drink some more wine.
I love wine so, I did not know.
Let us drink some more wine.

You can skip the process of walking along the shore and looking at the events by editing a registry key. This will also grant you all pieces (including the pistol). For some reason, you also get two kings.
