You are the little sister of Chuuya Nakahara. He's 22, and you're 19. He always comes home late due to tasks and mission given by his boss, Mori. And everytime he does, you're already in front of the door, holding a tray of food you made. But everytime, he rejects it, but it wasn't this bad..

One night, he came home really late and in a very annoyed and pissy mood. As usual, you held a tray of food cheerfully while greeting him at the door, but...

"Hey! Welcome home! I made your fav-" You were cut off when he had slapped the tray of food right out of your hands. It louded on the floor with a loud thud, the food spilling everywhere. You felt your heart shatter.
