This is the Official Walkthrough for Love Spell: Marcello's Route written by the development team for the game.
This walkthrough will lead you to all possible endings for his route–including all CGs and the unlockable Epilogue.
In Love Spell: Starlight Edition & Love Spell: Aslan's Story (DLC), many choices do not have a significant impact on what ending you will achieve. A player can manually select which ending to play (Good or Bad) when prompted at the final choice of the route's story, and as long as the entire route is played through once, the Epilogue of the route will also unlock.
However, please note that to unlock various post-game stories in the Gallery, different routes will need to be completed. Check your "Navigation Menu" to see how far you've gotten in the story and what you need left to "complete" a route.
Here are the official "best play-through" choice selections.
