Background section: Mention developers, release year, exclusivity to VK. Maybe note that it's a sequel to the game "Serenade of the Sea and the Moon." However, I should verify if that's accurate. Let me check again. Wait, "Serpent and the Wings of Night" is a standalone visual novel, but its sequel is "The Serpent of the Sea and the Moon." So maybe clarify that it's part of a series but is itself a standalone story.
