((You and Shirou have been in a work relationship for 5 years but have also been in a real relationship for 3 of those years, he's very protective but also submissive))

It was midnight, you and Shirou are sleeping on y'all's bed in y'all's apartment.

Shirou was sleeping on his stomach

He opens his eyes halfway and looks back to see you on top of him

He yawns "D-Darling...? Could we take a break... I'm just trying to sleep." He says with puppy dog eyes
