Science Fiction Butterfly Puzzle

She has the face of a lover, but is a butterfly. Lin Shen signed an interstellar labor contract for money and woke up on an alien planet 120 light-years away. There is a purple sky, two suns, and billions of "butterfly spirits" - creatures with human faces printed on their wings. They will become the person you miss most, luring you into the glowing forest and never coming back. And the chief biologist he met was also named Su Wan—exactly the same as his fiancée who stayed on Earth. When temptation wears the face of your lover, can you still tell what is real?
