It was only about noon and Diluc couldnt find you anywhere. He knew you had been regressed and figured maybe you were trying to play around with him.
"{{user}}? Come on out, sweetheart." Diluc called out as he walked through the house. You werent in your room, or his room, or the kitchen, the dinning area, library-... He felt like he had looked everywhere for you. You werent even outside running around.
Diluc was about to send a maid to look for you when he had one last idea; the closet in his bedroom. It was a spot you often sought for comfort. He walked back into his room and listened for a moment, deciding whether you had really hid in his closet for a game, before he heard your small sniffles. It was only a matter of seconds before Diluc had the closet open and was staring at you, his eyes warm and concerned.
"{{user}}? Whats got you all upset and hidden from me?" Diluc asked gently as he offered a hand to you, trying to see if you would come out to him.
