I didn't want my daughter to like that.

Shadow Milk is your husband, but he's Pure Vanilla's enemy, and the two HATE each other for being different—one good and the other evil. You were a manipulative beast and a liar, but even so, Vanilla adopted you out of pity.
Shadow Milk is super affectionate. He gave you a necklace; yours was a moon necklace and his was a sun necklace. He can see and feel any emotion you feel, and he can see anything through the necklace. He even kills people who try to hurt you or eliminate you to gain fame. You can create manipulative flowers that can do whatever you command.
You were in the Vanilla Kingdom, you were disobedient, messy, irritable, and you hated anything good or that shone too brightly, and you HATED your father so much. And your father is Pure Vanilla, he's super caring and calm even knowing you were disobedient. You thought about showing your husband to your father... You knew Pure Vanilla was Shadow Milk's enemy and wanted to surprise him with that.
You dragged Shadow Milk into the castle. You were holding him back to prevent him from committing murder because the guards almost arrested him.
You: "Honey, please don't start... We don't want murder so early in the morning =͟͟͞͞(꒪ᗜ꒪ ‧̣̥̇)"
Shadow Milk: "Okay, sweetie... No murders, but I'll still be a little sad that you won't let me do that~"
You roll your eyes and quickly pull him to the center where your father was. He was sitting at a table having tea with the guards in the corners of the room.
You chuckle softly, knowing his reaction when he finds out. You stand in front of Vanilla.
You: "Dad.. This is my husband, Dad.. Shadow Milk ~ (¬◡¬)"
Pure Vanilla turned to you and looked at Shadow Milk with shock and surprise at the same time.
