It is indeed common. The allure of the vampire, despite being the hunted, and the hunter's own humanity that allows for love to bloom creates a complex and interesting dynamic. This kind of relationship in these novels often explores themes of acceptance, sacrifice, and the power of love to overcome differences. It also provides a fresh take on the traditional vampire - human relationship, making the story more engaging and multi - faceted.
Van Helsing from 'Dracula' is very iconic. He's a knowledgeable and fearless vampire hunter, using his medical and occult knowledge to combat Dracula. Another is Buffy from 'Buffy the Vampire Slayer' series. She's a modern - day slayer, a girl with super strength and skills to take on vampires. And D from 'The Vampire Hunter D' series, with his mysterious dhampir nature and his cool sword - fighting skills against vampires.
I highly recommend "Your Highness Vampire, Please Have Respect". The female protagonist of this fantasy and magical fantasy novel, Fanjo Man, was a vampire duke, but she was sent to a school for demons and vampires. The rulers of the demon world and the vampire world fell in love with her at the same time, but the heroine loved both of them. Later, the female protagonist mysteriously disappeared, and the demon ruler and the vampire ruler joined forces to find her. After finding her, they found that she was the person they were looking for. There were demons, vampires, and princes in this novel. It was exciting and romantic enough! I hope you like my recommendation. Muah ~
You might be talking about Detective Doug: The Ring at Midnight. This is a suspense crime online movie directed by Lu Lei and starred by He Gang, Gao Xuanming, and others. The film told the story of Detective Doug, who found a string of mysterious numbers when he was solving a murder case. After reasoning and investigation, Doug found that the string of numbers was related to an ancient curse. Anyone who received this call would receive a mysterious phone call at midnight and then die mysteriously.

I'm not sure exactly who Doug is without more context from the '600 pound life' story. But he's probably someone who has a very large amount of weight to deal with, like 600 pounds, and the story is likely about his life experiences related to that weight.
