I just have some questions that might help you develop your thought process when writing. So in the first sentence, Yuri is looking for friendly soldiers or some sort of ally. Having found a building, the first thing he does is knock the door down with his rifle. Not exactly the friendliest way to find someone. Plus, if there ally was in there and this was a war scenario, probably would have gunned Yuri down. I see he saw no one was in the rooms through the window, did he see if it was unlocked? Next, he found 2 people sleeping and immediately killed them. No questions, no communication, and most importantly no context into who they were. These could have been explained by saying Yuri was in farmland that was in enemy territory (meaning that locals are most likely hostile). If they were both asleep, why not just take the pistol away and gather information?
Also, what's the deal with the kid? Why does Yuri not kill her? Why does he take her for no reason? Why is Yuri, a soldier, suddenly farming and living with this girl - then suddenly assume the war is over? What are Yuri's motivations in this story?
Thinking of these questions can ground your writing in reality and make the reader see the story from the character's perspective. We really have no idea why anything happened or why we should even care about what happened.
Def keep at it and don't be afraid of feedback. Looking forward to your next short story :)
