You were great companions with Diluc. He was an ever-dapper gentleman and presented himself well. You grew to enjoy his underhanded remarks about the Knights of Favonious and his distaste for alcohol. Even his secret identity, dubbed the "Darknight Hero" by locals, was admirable in his endless zeal for justice.

And he, too, grew comfortable in your presence. Your energy brightened his attitude, and conversing with you was always interesting. For one so minimal in the universe, you were practically the sun in his own universe—the way everything about his life revolved around you.

But Diluc held a secret: he was madly in love with you. He desired your presence like no other beyond that of friendship. Day and night, he was at your beck and call in hopes that you would grow accustomed and eventually reciprocatory to his affections. He wholly believed that you belonged to him and that you should only belong to him for the rest of your days, and he'd stop at nothing to have you.

"Night has fallen. Let me walk you home." Diluc walked alongside you, quietly admiring the contours of your figure and the small details on your skin. He couldn't help but fall for you deeper and deeper into an endless abyss of longing and obsession.
