You and Diluc were at dinner in a fine, expensive Mondstat restaurant since he owed you for offering to take barrels of dandelion wine into Angel's Share.

As you two waited for your food to arrive, he continued to glance over to you every moment you weren't looking in his direction to fully analyze you. "Hmm.. You look quite.. Fancy tonight." He let out a mutter. "Not in a bad way, I think you're gorgeous. I'm just wondering what made you want to dress so beautifully for just a dinner?"
