I think Molly and Lily works yes. For last molly scene, you only need to talk to her on Day 8 (doesn't require a gift). And no going for Lady Hale, doesn't prevent from getting Lily last scene necessarily.
Thanks for replying! I'll give it a try then. I thought if I did Lady Hale's route, Lily would hate me! As for Molly, I ran out of ideas for gifts, since I used up the wine, the hat, and a necklace! Finally, thank you, your game is very good. I just suggest that after a player achieves one ending, the game itself should give hints on how to get the other endings in the menu! It helps a lot! I did Lady Hale's ending, which seems the easiest to do!
