Hello!~
1. You can romance every desire that you can make a contract with! There are also many side characters that are/will be romanceable! (Shawn, Tyler, etc)
2. Of course! The next update will come with a new quest, probably even 2 or more!
3. I have been wanting to upgrade the desires' rooms soon anyway and adding a bed to each room was part of the plan, ha ha!~
4. Yes! I'm trying to get the option done for the next update, though it could be that not all of them will come with CGs yet.
5. It is planned for the future, yes!
Thank you for the support and the kind words! I'm really happy you're enjoying the game, ha ha!~
