Cons first
Awkward sentence structure. Try reading it out loud.
Backstory in the beginning ruins it all. There's no mystery anymore and it diffuses the suspense. You basically know who he's running from, and why. Try to spread it out or not be so revealing.
You talked about a window for three paragraphs.
You described a kitchen. We all know what one looks like. Unless there's something important in the kitchen that the reader should know about, any mention of stoves or fridges is redundant.
Your dialogue is slightly unbelievable. If you listen to a regular conversation, no one talks in full sentences. There's also too much unrelated dialogue.
Pros!
Grammar, a couple mistakes, but overall very good.
Descriptions of actions while people were talking were done well.
No overuse or repetition of adjectives.
Nice diction.
Keep it up!
