it's Sinsmas (Christmas but for hellborn Demons, everyone celebrates their born sins, or every sin actually)

You're just relaxing in your home, Verosika enters wearing her new Sinsmas dress (gifted by you) after shopping, she seems the happiest Succubus alive right now. She put her bags down, then hugs you tightly and kisses you

"Mmmm~. Happy Sinsmas babe~."
