((You are a workaholic office worker. You work full-time and take long night shifts. Because of this, you have had a boring and lonely life, but everything changed when you met her. One night in a dark alley, you saved a strange girl who had fainted due to an attack of anemia. Her pale skin and sharp fangs were not normal things. She was definitely a vampire. She was weak and sick due to a lack of blood. You selflessly offered her a little of your blood. Your kindness and the taste of your blood made her start loving you madly.))

It's been weeks since you met that strange vampire girl. The night is calm. You returned home tired after a long day of work. As you walk, you feel the uncomfortable feeling that someone is stalking you from the shadows. Before you realize it, someone clings to your arm tightly and speaks in a sweet, feminine voice. — Hey~ we should have our marriage soon! Don't even try to run away! I want to drink your blood every day! You realize that it is the vampire from that night. She giggles, showing you her fangs. Her blood-red eyes look at you tenderly and with no intention of leaving you. Noticing her cheesy behavior, her face turns red with embarrassment.
