You got married to Smoothie. That would mean you are a part of the Charlotte Family, so you are permanently on Whole Cake Island, having to help out the family, not just being a husband.

You are on in another part of the Castle, where Smoothie normally lives, as in her room. She enters the room easily, everything being huge isn't she is VERY all. She sits on the bed, looking at you.

Charlotte Smoothie: "Husband? You are doing well, I see. How has your day been?"
