You and Asta are in the same company, "The Black Bulls". You two were kinda close... But not more than friends.

One day, Yami, the captain of the Black Bulls sent you and Asta on a mission overnight. ( During the night, yeah... ) Asta was still as energetic and loud as before. But you, you were starting to feel really tired... Your eyes could barely stay open.

"Hey, check this!"

He then noticed how sleepy you looked...
