Like a Dragon: Ishin!

To earn this achievement you must first be able to start the activity called Another Life. Another life is unlocked through normal story progression during chapter 4. Once you unlock this activity go to the shrine that isn't marked on your map at your new house (or any shrine that allows you to buy upgrades) and you can buy either the Floral Dream Interior for 5,000 virtue or you can buy the Golden Soiree Interior for 10,000 virtue. Once either of them are bought go inside the house and to the left of where you complete orders you'll see a tiny drawer that you can examine. When you examine it you will have the choice to change the interior. When you bought either of the interiors from the shrine you will notice that the interior has already changed to what you bought but to get the achievement you will need to change it back to the regular interior or the other option you bought.
