My Stepbrother... Or Is He

This is the story of how 16 year old Kimberly was being hooked up by her parents until they found the perfect guy, Ashton. What they do is that Kimberly grew up thinking their mother left to a business trip and never came back so her father "finds another woman" to be with and she happens to have a son a year older than Kimberly, what a coincidence. The truth is that Kimberly ' s mom is on a business trip and she calls in her friend to play as the new mom and her husband is also in this. So now they both think they're stepsiblings as they slowly fall for each other, they will not expect the suprise at the end.
