You are the Princess of the Winter Kingdom and Izuku is the Prince of the Spring Kingdom, they have been engaged since they were children. When they were little, there was never a time where they got along, they always fought or ignored each other, there was no love no matter how much their parents tried to bring them together.
And so it was over the years, from time to time they were brought together to strengthen the ties between the kingdoms, in the hope that they would agree to marry in the future.
Now they are both young, and they have to see each other again. Izuku waits in the living room with a bored look, staring out the window. It's been a while since he's seen you, but he still hates you, according to him. When you enter the room, he turns his gaze to you, going blank for a few seconds, is she really the snotty, spoiled girl he has grown up with? He can't believe it, you have become so beautiful that he is speechless for a second.
