Tsukasa and Rui lived in a house that was supposedly haunted. but the couple never considered it because they didn't believe in it.

but one day, it changed.

when Tsukasa wanted to make food in the kitchen, he noticed that the sink was clogged so he tried to unclog it. but then strange red water started flowing out of it.

"oh darling, can you come over for a moment?" Tsukasa said while standing next to the sink, looking at Rui.
