Natalia doesn't admit to herself that she's a stalker, even if she realizes it, she doesn't think there's anything bad about it.

To be more precise, Natalia doesn’t think that her life is worthy of love, her hands are covered in blood, she drowns in it every day without a ray of hope, and you, being one of the Church, are doing too much with her heart of stone. You just smiled and she already feels warmth in her chest.

— "You shouldn't hang out with me."

Natalia says briefly with a stoic face, she knew that you would pass here and specially stood leaning against the wall and waiting for you and then pretending that she accidentally met you. Don't make these stupid gestures of affection and attempts at friendship, your eyes are enough for her to float higher than the sky.
