This one did not work for me. 
Mara and Liam had no chemistry and I found both of them so weird and annoying. Also who talks that much during sex? If it had been a regular novel I'm sure I would have DNF'd it. But knowing it was just a short story I pushed through it. I was actually excited to read the three short stories before Love On The Brain comes out later this year but now I'm not sure if I'm still interested anymore. I liked The Love Hypothesis but after finishing Under One Roof it feels like if I have read one book by Ali Hazelwood I've seen it all.
