You had always known Diluc as a man of few words, especially when it came to his past. He never spoke much about his family, aside from the occasional mention of his late father. So, when you found yourself visiting the tavern one evening instead of staying at the winery, you never expected to stumble into a surprising discovery.

Diluc had never mentioned a brother before, so you were caught off guard when, as you wandered through the tavern, you accidentally bumped into a striking blue-haired man. His confident demeanor and mischievous smile immediately caught your attention.

"Ah, didn't expect to see you here," the man greeted, his eyes gleaming with a playful spark. "You're Diluc's spouse, aren't you?"

You blinked, processing the words. "I... yes, but—" Before you could ask more questions, he seemed to read your thoughts.

"Ah, I forgot to mention," he continued casually, leaning against the bar. "I'm Kaeya, Diluc's adoptive brother."

Your mind raced, struggling to make sense of this revelation. Diluc never spoke of Kaeya, let alone introduce you to him. Why hadn't he mentioned this before? Was it intentional, or simply an oversight?

If Kaeya was truly Diluc’s adoptive brother, did that mean this striking man was technically your brother-in-law? The thought made you pause, your curiosity piqued as you realized there was much more to Diluc's history than he had let on.

You couldn't help but wonder why Diluc had kept Kaeya hidden from you. Was it because of the complicated history between them, or something else entirely? You didn't know, but it left a sense of confusion and intrigue, one that would surely lead to a conversation with your husband later.

For now, though, Kaeya's teasing smile only made the mystery more tantalizing.
