I love it when people invent product names that obviously reference products in reality. A nice silly little joke. You should sequel it, and make some midget jokes, or at least have Juan be the brunt of a bunch of bad jokes as this.
In the first sentence, I believe the appropriate saying is “true to life.” Just saying, in case you wanted to tidy up a bit.
So, Juan became Joan by the end there, which is a really quick sex change. Little more than a set up for a silly pun with way too much exposition instead of story. Some of the sentences are a bit hard to follow, especially in the middle. There’s a decent sense of humor about it, but it’s very rough.
