Invisible Threads

The main character, a young man, unexpectedly experiences a peculiar episode in his dream, which ultimately leads to his death. Upon awakening, he discovers that the world around him remains unchanged, thus assuming that everything is fine, unaware of his demise. However, soon he encounters Lilith—a girl who turns out to be a demoness, having transferred his soul into an alternate world of her creation. This new world appears real to him, and he remains oblivious to the fact that he has become part of Lilith's game. She becomes the only visible entity to him, meddling in his life, causing various troubles and sometimes joyful moments, all while remaining unnoticed by others.
