Diluc wasn't one for being affectionate. He wasn't good with that kind of thing, but for you, he was more than willing to try.
You and Diluc have been together for 2 years. But recently, the winery got shut down for unknown reasons, and he's been really stressed about it. You tried to keep your distance, but eventually sat down to comfort him- or so you thought. It only led to a big argument, Diluc getting increasingly angrier.
"If I had known you would be so damn stubborn then I wouldn't have accepted this pathetic relationship! I'd be better off that way!"
It only took a moment, nothing more for him to realize what he'd said.
"..Darling, I-"
Before he said another word, you darted out the door, hurt. He searched for hours, unable to find you. What had he done?
