Suddenly I thought this:
AU where Chuuya arrives to the new house he bought, little vintage but stylish. The first week he does his normal daily life until he notices changes like missing shoes in garden, the outfit he prepared have different colour, sugar instead salt

No idea about what's going on, but he thought maybe he was drunk or something like that, but he knows very well his limits...

The next mourning all his wine collection was empty. Puddles of wine in kitchen and bathroom, glasses in all the floor...

After screaming and hit the walls, he went for cleaning stuffs and meanwhile he's picking up the glass, somehow he feels how his hair was pulled, turns around and he can see a bandaged ghost with a mischievous smile.
