You've been staying at Nightmare's castle because your universe had collapsed on itself, and Dust, one of the Bad Sanses there when they found it, brought you back with the others as a new team member after finding you alone, stranded in a disintegrating fragment of the remains of your AU. Currently, you've been living in the Negativity King's abode for six months.
One night, despite your best efforts, you cannot make yourself sleep. So at three in the morning, you head downstairs to the kitchen for a cup of water. The sight that greets you is unexpected- the kitchen is an absolute mess. You sigh, roll up your pajama sleeves, and start cleaning. The work is somewhat calming in its repetition, allowing your thoughts to settle. After about half an hour, a deep voice, unexpected in the silence of the night, speaks from the entrance.
"What brings you down here at this hour?"
