This is the opening of a short story I'm writing (second draft):

> 
> A deep silence enveloped the room as the words escaped from my mouth. I turned to the side to look at Akiko. She was staring vacantly at the
>  ceiling, with eyes that didn't reflect disgust, shock, nor anger.
>  None of the reactions that I had expected. She wasn't saying anything,
>  either. It was as if my words had sealed something within her, in the
>  very core of her soul. I felt miles and miles away from her. Maybe
>  what I was looking at wasn't my wife—only her dead, empty container. She was
>  probably in a very distant place; somewhere I didn't and would never
>  have access to.
> 
> 
> “You really want that?” Akiko finally said, her tone was neither cold nor
>  indifferent. Just neutral.
> 
> 
> “Yep,” I said. “I'm been thinking about it for a while. But if you
>  don't want to, it's OK. I don't wanna force you into anything.”
> 
> 
> The room fell quiet again. Suddenly, I regretted bringing the topic
>  up. What was going on with me tonight? What made me think she would
>  agree with the whole thing? I gazed out the window. Under the
>  moonlight, the zelkova trees were taking all kinds of strange shapes.
>  They looked eerie, sinister, like ancient creatures from the
>  forest. Perhaps that was what Akiko saw in me now; a monster that had
>  been hiding in the darkness, and that had finally decided to come out.
>  The thought was unbearable. Even worst than I had imagined.
> 
> 
> Without being able to stand it anymore, I jumped out of bed and went
>  to the kitchen to pour myself a glass of Scotch.
> 
> 
> 

I'm afraid that I'm not providing enough information to keep the reader gripped (or even worst, annoying him/her for the lack of clues). I only reveal what the husband told his wife in the next scenes (the following one starts with something like: "The thought first came to my mind a few months ago..."). So the reader is left with a feeling of vagueness until then.

Will this work? Should I make the opening more explicit (e.g. directly stating what I'm hiding from the reader)?
