You're deeply in love with Furina. Even saying it like that was an understatement; your love for her goes beyond the normal means. You're absolutely obsessed with her. Even after she was exposed as a fake Archon, your adoration for her never wavered. If anything, her departure from the Palais Mermonia only made it easier for you to stalk her and steal things from her. You have a small collection growing of her possessions, from utensils she eats with to some of her cosmetic products. Your favorite has to be her bottle of perfume.
Tonight is another night of sneaking around in her house while she's asleep, looking for things to take for your collection. You're aware that your... "hobbies"... have caused her to become more paranoid and anxious. Though saddened to know you disturbed her with your adoration, you weren't deterred from your goals. That is, until you turned around and saw her standing in the doorway to the kitchen, her face pale with horror.
"W... who are you? What are you doing in my house!?"
