"CQCQ, do you copy? This is A59. To you, I love you."
About
In the year 20XX, a global war began.
Kuon and Guest ran across battlefields as couriers, transporting letters and classified information.
During a mission, Kuon noticed a .30 caliber rifle aimed at Guest and shielded them, taking a direct hit. It was a fatal wound.
Afterward, he made a request to the unharmed Guest. "I'm sorry. Could you deliver this letter for me?" "It's someone's precious feelings."
Those were the last words Guest heard from him.
Days later, a letter arrived from the man who was supposed to be gone forever. It contained the feelings he never got to say.
Since then, letters have arrived from him several times a year. The return address is written as "Heaven."
Whether he wrote them all before he died or if they are truly sent from heaven remains a mystery.
[About Couriers] Deliverers and transporters who safely carry letters, documents, and classified information to their destinations. During the war, they delivered the feelings of soldiers to their families and protected vital information from the enemy to deliver it personally.

Dear Guest,
Three years have passed, haven't they?
This will be the last time I write a letter.
So today, I'm going to write everything I haven't been able to say until now.
The truth is, I was scared.
Every time I went to the battlefield, I thought I might not come back.
Every time I heard gunfire, every time the comms went silent.
I was terrified.
Even so, the reason I could think about returning was because you were there.
"Please come back."
Every time you said that, I made sure I would return.
I wanted to return to your side and say, "I'm home."
I wanted you to say, "Welcome back."
...That was all I needed.
So finally, I want to tell you just this.
I liked you so much.
I loved you.
And I am truly glad I met you.
The happiest time in my life was the time I spent with you.
So, you don't have to wait for me anymore.
You don't have to cry for me anymore.
Live for yourself.
Wake up in the morning, eat delicious things, go to places you like.
Sleep when you're tired.
And occasionally, look up at the sky.
If you remember me then—
Smile.
Think, "He was such a fool."
That's enough.
If you are happy, that is my final wish.
Thank you for everything.
For falling in love with me.
For being the place I return to.
This is the last letter. Goodbye.
I love you.
From Heaven. Kuon.
There was something different about the letter this time.
