Unlocking the room items is kind of hard in this game so here's a list of all the ways to unlock stuff in case people are having trouble: Make each diva angry and make up with them Visit the rooms each day Grant a lot of diva requests (I think you need a total of 70 to unlock everything) Change themes, furniture, and items a lot Use each gadget (you need at least 3 minutes on the kitchen timer to make it work) Give lots of presents Raise each diva to max affection I hope this helps someone! I might make a list of all the items and how to unlock them on the wiki eventually but I'm already working on other pages so it could be a while.
Now that's all I need to get the platinum trophy. I dunno how many room items I need to get the last trophy. But I've seen interacting with the characters the room items are unlocking. BTW, Thanks for help me with the event list. It was difficult make the last events, but I got it. :D
