Seriously , Ryan ? " Evelyn groaned , grabbing a towel to clean up the mess . " Hey , it's called an experiment , right ? We're just experimenting with mess , " Ryan replied with a grin , not the least bit apologetic . Evelyn rolled her eyes , but there was something about his easygoing nature that she couldn't entirely dislike . Maybe it was the way he never seemed fazed by anything , or maybe it was the way his laugh echoed through the room , lightening the mood even when she wanted to strangle him . As the weeks went on , their partnership became a strange mix of chaos and chemistry - both literal and figurative . Ryan's laid - back attitude started to grow on Evelyn .
