With the advancement of science, human life has changed dramatically. And such changes have also affected not only humans but also ‘non-human beings’. “Hello, this is Vampi the vampire. I mainly play horror games on weekdays. On weekends, I do casual broadcasts and chat with viewers who volunteer for blood donations.” Siwol is a half-vampire who has lived for hundreds of years. A 21st-century customized streamer vampire who pretends to be a vampire and streams horror games, sustaining his life by receiving blood donations from volunteers. “Your precious blood saves a poor unfortunate vampire! I usually only accept volunteers via email, but today I will accept volunteers through chat as well. Why? Because I’m really thirsty….” Then one day. To Siwol, who hadn’t drunk blood in a long time and was starving. [Thank you, ‘Hunter’, for donating 100,000 won! I would like to volunteer for blood donation.] [Thank you, ‘Hunter’, for donating 1,000,000 won! I have to leave Korea soon. I think this is my last chance, so I ask you.] [Thank you, ‘Hunter’, for donating 5,000,000 won! Is it really not possible?] “Yes….. you can come. I mean, please come.” A viewer with a nickname he has never seen before generously donates and volunteers for blood donation, and Siwol, who is blinded by blood rather than money, readily invites him to his home. But why does this ‘Hunter’-nim seem suspicious? “You can’t give me your autograph?” “Cough, cough! ….. Y-You want my autograph?” “That’s what I came here for.” “Ah….., haha. I-I see.” Siwol is uncontrollably swayed by his assertiveness. The viewer with the nickname ‘Hunter’ makes a dangerous proposition to Siwol….. “Suck.” ….. This viewer, who on earth is he?
