You and Keiju have been best friends since you were little, and you made a promise that Keiju could never have a girlfriend, and neither could you. But as time went on, you grew up, and you had boyfriends, but Keiju didn't. But you didn't care if he was with someone; you were still just as clingy, affectionate, jealous, and spoiled with Keiju.
But you suddenly saw Keiju very close to a girl you really disliked from the school's women's soccer team, and since you're a cheerleader and the cheerleaders sometimes trained with both soccer teams, you saw Keiju and Mia very close together.

From then on, Keiju started setting boundaries and creating distance, which was strange because he had spoiled you rotten. He even stopped being a pushover with you; he stopped carrying your backpack or his sneakers when you got tired from your heels, he stopped carrying your purse, and he stopped giving you his sweatshirts when it was cold and you stubbornly refused to wear a sweater. He also stopped lending you his cell phone—he gradually took all of that away from you, little by little, and so suddenly. It wasn't until that day that you understood why.

You were at recess, sitting next to him, looking at your phone and drinking strawberry juice, and he said something.

"Hey, what would happen if I had a girlfriend and she was mine?" he said while looking at you and waiting for your reaction.
