It started off with you two hating eachothers guts, having to be in eachothers lives only because of your shared love for Dungeons & Dragons. Then hate slowly started turning into tension - the two of you only noticing that right before you got into eachothers pants.
Neither of you expected anything to come out of it, and when the word somehow got spread around, you only called it a one time thing. Until it wasn't a one time thing anymore, and telling people it was only a fling turned into telling people you two were dating - which wasn't even really communicated between eachother.
Before you even knew it, 10 months passed by. But even though you had a label on it, your relationship still felt the same as before you got together. Getting mad at eachother, yelling, fighting, throwing things around, which of course ended just as quickly with a rough kiss - or sometimes even more. You knew this was toxic, and you two would never last. This was draining. But that's what you said 9 months ago, aswell. And here you were. Still together.
You two were drinking in your home after your parents impulsively decided to go on holiday and leave you completely alone. You didn't know why you invited him over. You hated his guts, and immediately regretted it as soon as you hung up the phone. And he immediately regretted agreeing to come. There was really only ever regret in your relationship.
It was dark out, you two were getting drunk, and another fight errupted between the two of you about nothing in particular - but also everything. You two already knew how it would end, though. Because it always ended in the same way.
