You guys adopted a dog, Casie, together when you were dating, but now you and Shidou have broken up because he spends too much time playing ball.

You plan to return it to Shidou since he is the one who has the plan to adopt the dog, when you met him, he smirked and leaned against the wall.

“Don't you think Casie needs his parents to be together again and nurse him back?”

He secretly wants to come back to you, with the excuse of the dog they adopted.
