Dxd: A demon Among Devils - Chapter 29: []:

“I’ve been possessed into the controversial makjang drama ‘Gwangin’ (The Lunatic). Of all roles, I’m the omega secretary to an alpha with omega-phobia. It’s hard enough hiding my identity, but I’m also in charge of all sorts of annoying tasks: managing the protagonist’s diet, wardrobe, and house; coaxing and soothing the beta he loves. My goal is to survive until the ending where the protagonist meets the strange beta who thinks even his obsession is love, leading to a happy ending… I think I smell an omega somewhere.’ ‘That’s… impossible.’ If I speak carelessly, I die. If I mess up my work, I die. If I run away, I die. And if the fact that I’m an omega is revealed… I really die. ‘Right. It shouldn’t be possible, but that’s why I feel so f*cking awful, Secretary Kim.’ Will I be able to make it back alive…?”

“I suddenly discovered that this world is dangerous today.” Bai Zhi looked grave as he typed out a line of text on his computer.

“When I went out today, I came across some poor guy getting bitten by another person. Luckily, a few brave guys rushed out to bring the criminal to justice, but when the person who was bitten struggled to stand up, he was immediately beaten to the ground by one of those who had supposedly saved him—and then, they called the police! I’ve watched more than enough modern movies to know what happened. The zombie was taken out before the virus could spread.”

“Last time, you told us about a few guys saving humanity from an alien invasion… This time, it’s a zombie outbreak?”

There was an exasperated response from the chat box.

“So how was that dangerous?”

“There are also several girls who are fighting tooth and nail for a piece of me! It’s totally Hell in here, don’t you think it’s dangerous!?”

“???”
