How to change the "Interior decoration"?

In Kawaii Mansion, you can decorate the Mansion to your liking ^^~
*First, you will be given a task to unlock rooms or specific items needed for decoration.
- After completing the scene, you will receive the Star. (What's Star?)
- The Star will unlock that task (rooms or specific item) for you.
- This is the first time you change the decoration of that piece of furniture so it will be completely free.

*Change decorations by NPC's request.
- Sometimes while chatting with you, NPCs will suggest you which items they want to change, and you will help them do it.
- And of course you will be free.

*Change decorations by your liking.

- After going through the unlocking screen, or changing the interior at the request of the NPC, you still have the opportunity to choose other "options" if you change your mind.
- Hold for a few seconds on the item you want to change (a list of other options will appear)
- However, on this change, you will need to watch ads or pay with Coins (depending on the item you choose).(What's Coin?)

**Note :
Sometimes there will be some furniture items that cannot be changed because they are "default" or have not been updated with new options.
