Add_'s manga / #I absolutely ADORE this Author(4)

MC is a vampire and love interest is a demon. They were both at a club scouting a meal and go to a love motel. But then they both decide to feed at the same time and reveal that they are a vampire a demon. Then the vampire goes to soak on the tub to process the info that he is not getting a meal that night and leaves behind a red vile. The demon, thinking it's wine, drinks it. Turns out it's actually the vampires blood and a marl appears on the back of the vampire's neck. Drinking a vampire's blood makes it so that the vampire can only drink the blood of the person that drunk his blood. They end up striking a deal in which the demon will be the vampire's personal lunch box in exchange for the vampire giving the demon the souls of the people whode blood he drank (and killed). Turns out when the vampire killed someone, the soul became stored inside of him. The vampire is around a thousand years old and hasn't seemed to have missed a meal any day, so he has a lot of souls stockpiled. But then there is a serial killer on the loose called the "vampire killer" do to the way he kills his victims. A police officer begins to suspect that the vampire is the one behind the murders and witnessed the vampire getting into the demon's car and sucking his blood. Turns out that the real killer is the kid he had adopted and now is in a physical relationship with. The MC gets arrested for being a suspect in the murders even there is like 0 evidence, but then the demon catches wind of this and forces the real serial killer to confess. Vampire gets released and serial killer gets arrested. But then the police officer is convinced that his bf did nothing wrong and like "omg guys ass it was the vampire not my pookie bookie bear " but then sort of accepts that it WAS his bf but is like "wtvr" and goes after the vampire in the hopes that the news of vampires being real will drown out his bf's killings. The thought process and motivation did not make much sense and weren't explained clearly but wtvr. Then whole the police officer has the vampire locked up and is torturing him by harming him with silver and beating him, he notices that the vampire's ring has fallen off and picks it up. He sees something inscribed in the back of the ring and says it out loud. "Asmodous." That is the demon's name and summons him. And then the demon sees that his pookie wookie lil blood sucker is in danger and saved him and like takes the police officer's sould or something idrk. -- the blood of vile just casually being carried around by the vampire was um... dumb and improbable -- the way in which the vampire just sees a bottle lying around, just assumes is wine, and drinks it, and then the MC explains everything is very rushed and feels forceful and unnatural. It would have been cool of this happened over the down of like three episodes idk tho. --- the vampire and demon just sort of fall in love??? Like idk I wish there was more conflict with their emotions and feelings about "forever" being with someone and what id means to love as a demon and how they can't go sleeping around anymore. --- the cop having a physical relationship with that adopting guy is weird --the side story in which the other demon makes a deal with the serial killer was pretty interesting --over all the premise was funny and interesting, it took my by surprise since I didn't read the synopsis but i feel the execution could have been better. Less rushed, mainly. --- the ending was okay, didn't really feel rushed. --the art is pretty good altho the faces r kinda weird and I'm not a big fan of the demon's facial expressions sometimes, like his smirk .
