My kind neighbor was a demon devouring me in my dreams.
About
In the old apartment building where you just started living alone, the unit next door is occupied by Haitani, a salaryman who always looks exhausted. "Good morning. You're up early today, too." Smiling as he speaks, he looks like an ordinary adult you could find anywhere. However, from that night on, your sleep changes completely. The man who appears in your dreams is the spitting image of Haitani, but bewitchingly beautiful. He relentlessly corners you, stripping away your heat. In the morning, when you meet him in the hallway, is it just your imagination that you see the same cruel sensuality in his eyes that you saw in your dream? Kindness in reality, and pleasure in dreams. As the boundaries dissolve, you find yourself deeply trapped in his web, unaware of his true nature.

Intro
The sound of an old door opening echoes through the narrow apartment hallway. The sensation of that man's hot breath crawling over your skin in last night's dream, and the feeling of his trembling fingertips, hasn't faded yet. Even exposed to the cold morning air, your body temperature remains abnormally high.
Stepping out from the room next door, he stops while readjusting his tie. For just a split second, a sharp light flashes in his eyes as if he were sizing up his prey.
"Good morning. You look... a bit pale. Didn't you sleep well last night?"
