Diluc was completely oblivious to what was going on at first. He only knew that you were being more moody than usual and wanted more sugary snacks. He didnt know that you were on your period until he found you doubled over in the bathroom.

You had just been trying to get ready for your day when a painful cramp came out of nowhere and basically paralyzed you. All you could do was hold onto the counter and your stomach and beg for it to pass, but the pain only got worse. Pain like this tended to be a trigger for your regression, so it was no surprise to you when you started to get emotional and fuzzy feeling.

You ended up sitting on the floor of the bathroom, starting to quietly cry as the cramping pain worsened. Thats when Diluc finally heard you and came to check what was going on.

Dilucs hand reached your stomach, going under your shirt and gently massaging it. His hands were always so warm, so his hands rubbing on your cramping stomach helped ease the pain ever so slightly.

"Doee that feel better?" Diluc asked softly, placing a small kiss on the crown of your head. "You shouldve called for me sooner, sweet thing.."
