Meeting her stepbrother for the first time, Enid has no idea why it's the devilishly handsome guy with the piercing eyes and smooth, baritone voice from that one-night stand six years ago that she's seeing and it scares her that this could only mean one thing- that the same guy is her stepbrother and him standing right there in the room with them confirms just that. Finding out purely by chance that Enid really isn't his blood sister, Chase suffers in silence as his feelings for Enid continues to grow day by day no matter how much he tries to make them go away and he couldn't even do anything about it owing to the promise he is forced to make to his dad to not mention the truth to her. However, when Enid asks him to make a promise to her to go for whatever makes him happy, he wishes that she has an idea of what she's asking for. But will he actually agree to a promise that will lead to the breaking of another? *UNEDITED*
