I do like it better than this story, but stories like that tend to crash and burn really easily (and a lot). Devilish Junior has better chemistry and dialogue but this has a way clearer progression and direction with the story so in a way they kind of swapped qualities.
At the point I'm reading right now (I'm on chapter 6), Devilish Junior is superior but I've seen plenty of stories like that fall quite hard because of the unclear direction (and they can be quite fast too). I just hope they handle the inevitable reunion with the ex better than many others.
Edit: Ok... on chapter 12, Now the story of Devilish Junior is getting pretty annoying.
