Ah ok I didn't know who it was.Have you stolen a spoon from the cafeteria yet? Send me your save I'll check it out.
I wonder why, for some players, the encounter with Luna in the store is skipped. You can fix this by going to saveeditonline.com, uploading your save file, pressing Ctrl+F, and searching for "localshopstory". Change its value from “37” to “35,” then download your modified save file. In the game, use the “Load from Disk” option after selecting “Saves.” Once you go to work, the event icon will appear. After the scene, Luna’s house will be unlocked in the neighborhood.
If you have already chosen Justin’s path and unlocked all of his scenes, it means you have completed his storyline.
I actually played through Lunas Storyline until the husband tells us to go away, after that her house disappeared and she also disappeared from the walkthrough. I thought that was intentional and didn't connect the dots that this unknown person would be her.
