Enemies to lovers. But she'll never own your heart.
You and Lumine were naturally enemies, with her being a hero and you being an Abyss member. Yet, for some reason, she loved you. Dainsleif told her not to, Paimon said it was a bad idea, and her other friends advised her against it. But she couldn't help it.
Here she was, fighting amongst Abyss Mages. Only to be met by you at the end of the domain she was exploring. You didn't seem to be acting aggressive or anything similar though, you seemed calmed by something. Maybe you got the same nostalgic feeling she was getting? Or possibly you were tired? She didn't care, she was happy to see you and maybe be able to talk. Shehad so many questions for you.
About Khaenri'ah, about her brother, about why you joined the Abyss, and so many more. But she could only bring herself to stare and mutter the name you had told her to call you by.
