The Magic Lamp - Devilgram
"Levi gave it some thought fo..."
Leviathan specifies that nothing he says from now on is a wish until he confirms it, and MC can choose to go along with his ideas or not. After being able to interact with MC without worrying about the wishes, and after spending time with them, playing games and sharing his passions, he comes to the conclusion that he enjoyed that, and feels comfortable in MC's company. As he doesn't want MC to disappear from his life, Levi makes his final wish: he wants to live his life to the fullest and enjoy every minute of it together with MC. As the wish is granted, it breaks the spell binding them to the lamp. MC can then either kiss Levi, or thank him for setting them free.
