Despite the odd title this one was pretty cute.

Have the main couple who were dating BEFORE their father and mother met. During dating everything was going smooth till they broke up. A year later, their parents met, and married, and now they live together as brother and sister. Weird right? But it can happen, it's not that far fetched. The problem is these two have feelings for each other they don't wanna address.

Leading to a lot of funny moments, mixed with sexual tension, while learning how to live together. All in all, light hearted and fun, and something I enjoyed reading when I didn't think it be nearly as good as it is. A 4 out of 5.
