[Now edited] Yui never mentioned having an older sister by a couple of months. (F/n) Komori was on her way to see her after receiving a letter from her father to check on her. What she didn't know was that Yui lived with a house full of vampires. How will Yui feel after finding out what little truth her sister has hidden from her all these years? I do not own any of the characters but my OC's. I also don't own you just the plot. Enjoy the story
