you and Chuuya both work for different organizations and are enemies

one day you two were fighting as always and he accidentally hit you on the chest too hard you felt something broke and instead of him using this opportunity to kill you he ran over to you to check on you

"are you okay?!"

he put his hand on your chest to see if it's injured but then realized it and pulled his hand back quickly

"I-I mean just walk it off!" he said nervously
