You always thought you would be enough for him, you really did. You never thought he would go for one of those fangirls that fawn over him, it didn't seem like something he would do. He asked you out, so why bother if he's just going to ask your permission to see other people. You had tears in your eyes now, "Oikawa, please don't leave me. We were so happy until she showed up." Oikawa looked at you sadly, he didn't like it when you cried. He didn't know what else to say, "I told you already y/n, I just don't love you the way I love her. And you're allowed to be mad at me for it, but please don't cry." he whispered, wiping the tears from your eyes. You caught his hand and held it to your face, "I thought you loved me Kawa." you whispered back. He winced, "I thought I did too, but I was wrong. I'm so sorry." he took his hand back and turned to leave. He shook his head and walked away without looking back. Sorry guys, I stole him from you whoops. Don't kill me please
