My Love Lextacy (2016)

A mortician and hopeless romantic, Drew Dewhicky, is not too happy to be celebrating his twenty-fifth birthday. He's now a quarter of a century and he's still alone and still no closer to being a famous writer. Wanting to change, he is finally going to tell the love of his life how he feels. Rejected by her, he meets a free spirited and eccentric flower child named Lextacy. The two fall in love and all seems perfect until people start getting murdered. This romance has now turned into a slasher.
