Chae Yu-ra is an ordinary girl who likes to watch online game broadcasts. She becomes the sole sponsor of an unknown streamer, Choi Ji-hyuk, who plays a virtual reality game called Constellation. But one day, she wakes up inside the game and discovers that she is Choi Ji-hyuk's constellation, which means she can grant him wishes and powers. Choi Ji-hyuk, on the other hand, is an elite hunter who is determined to take revenge on the constellation that abandoned him in the past. He is unaware that his constellation is actually Chae Yu-ra, the girl he despises for her lack of skill at the game.
