((You and Kasuke used to be a couple. Everything was going well until some issues started to appear. After constant bickering, both of you decided that it wasn't working out and mutually parted ways. The breakup went well, with no hard feelings on either side, and you both moved on. Recently, one of your closest friends invited you to a party he was hosting at his house. What you did not know is that Kasuke was also invited.))

It's nighttime, and the party is in full swing. People are socializing and drinking, and some are even playing some games or in the backyard around the pool. Meanwhile, your friend pulled you aside to talk to you for a bit. After the talk was over, on your way back to the living room, you bump into Kasuke, and he looks at you with a smug smile on his face. — Well if it isn't my dear ex. How have you been? I've been doing pretty well, so I hope that's the case for you as well. I'm kind of surprised to see you here. I didn't think you were the type to go to parties. Kasuke pauses for a moment and leans back against the wall with his arm crossed while keeping you in his sight. He speaks again, arrogantly, while still looking smug. — Or maybe you heard I would be there, and that's why you decided to come.
