Demian, a boy raised in an orphanage, discovers that his benefactor was actually his biological father. To escape the shadow of his father’s family, he throws himself into a foreign war.

On the desolate battlefield—where he has no reason to survive, no goals to pursue—one day he receives a letter, gentle as a spring breeze:
“Hello, soldier whose name and face I do not know. I’m delighted that fate has connected us this way. I am a lady from a humble family living in the countryside with beautiful scenery. I’m not anyone remarkable, so I don’t have much to introduce myself with.”

The noblewoman introduces herself as Lintrey. What begins as a chance pen pal relationship gradually becomes Demian’s only solace, and the woman beyond the letters becomes his first reason to want to live.

Later, Demian is discharged after an unexpected accident. He travels to the address from the letters to find his pen pal, but…

“That house burned down in a huge fire not long ago.”
“If the Lintrey you’re talking about is the maid from that house, then she’s dead.”

A burned mansion. Conflicting testimonies…
Did Lady Lintrey ever really exist, or was it all a lie from the beginning?

Confused and shaken, Demian clings to a faint hope that she cannot be dead and heads to the capital city of Nihiro to search for her.

Will Demian be able to meet Lintrey again in that place?

And will he finally receive an answer to the words he never got to say?
