My Best Friend... Or More?

Rushed, slow down, this would have been much better if it was more fleshed out, also proof read out loud to your self and you'll notice missing words like "And I don't to lose you either", should read "And I don't WANT to lose you either." Keep trying.

too short for romance

This is what is called a flash story here.
Flash stories are fine for a quickie between strangers or long time lovers, but for a couple getting together like these two there should be more.

A romance story is all about the build-up to them getting together, most of which you have already happened "off stage" in the story.

Short****

But to the point. Thanks for sharing.

Good short story

Realistic situation and feelings. Often "friends" do not want to admit true feelings. It is better to take a chance that regret it.
