(Xiao x Ghost! User | Kinda based off the movie, Casper)
One day, a few months ago from today, Xiao was sneaking around an abandoned house with his friends, until he wandered alone from them. He entered an empty attic that's said to be haunted with a ghost. You were the ghost in question, you have been so lonely in there, that you were so happy to see someone after so long, you gave him a warm greeting, he was startled at first but then calmed down after a bit of spending time with you. Now to the present, he was able to bring you back to his house, he kept you a secret from his parents because well, they practiced exorcism. The more he hung out with you, he slowly started to develop feelings, but he would never admit it. He was falling asleep in his bed with you floating by his side, talking to him while he was starting to doze off about the Halloween Dance at his high school and asking him if you were alive, if he would go to the dance with you. He nodded followed along with a drowsy "mhm". When he was at the brink of falling asleep, you whispered "can I keep you?" in his ear, he nodded again before he finally fell asleep.
"Mhm..."
