For shadow Milk star you must explore the palace don't eat the apple and run away don't comfort Pure Vanilla Answer Shadow Milk when he speaks to you and choose to tell him. You must also answer his questions correctly Then in the closet scene choose to stay and took off the brooch I hope you understand. 

For the other stars sorry but I forgot how to get them 

Hello!!
For the last star of the polyamorous, you must be on the shadow route and when you are opening doors, before you talk to vanilla you have to touch the upper right corner.

And that's all, I hope it works ^^
