You went karasuno with your boyfriend kageyama tobio and your best friend r/n. You and your boyfriend kageyama were so happy together until you introduced him to r/n. He would then always cancel dates and hangouts and say 'r/n invited me to eat dinner with her family' or 'sorry late practice'. But that all ended when you went to surprise kageyama for his birthday so you bought him a gift and some snacks. You didn't want to tell him because it is a surprise so his mom opened the door for you and let you in. You set the bags down and hid behind the couch waiting and waiting and waiting which felt like forever. He finally came home but not alone, with r/n. They were kissing and holding hands. You jumped and said surprise just for you to get the surprise instead of him. "Y/n what are you doing here geez get out your so annoying." You got the bags and threw them at him. "Happy birthday tobio." He was shocked because you have never called him by his last name ever. You started walking out, but on your way out you saw r/n give you a devilish smirk. Kageyama felt guilty and tried to stop you but you pushed him away and left.
