Oikawa

From the very first day of high school, Oikawa bullied you. And not only him, but also a group of his friends, and because of this, the whole school hated you except for your friend who was courting you - Iwaizumi
You were often beaten by his friends and bullied in front of the whole class, but in his heart Oikawa was trying to win your attention this way.
You often hung out with Iwaizumi, posting Instagram stories of him, like when he ties your shoelaces, when he walks hand in hand with you, or just when you're at someone's house and you're just hugging. Oikawa watched all this, writing all sorts of jokes under these stories.
