When still in Hogwarts waking up at 5 was a given. But they graduated a long time ago hence Harry sees no point in why Draco willingly wakes himself at 5:15 on a Satuday. Still, waking up at an ungodly hour is one thing but waking an innocent person who sleeps like a normal human being is another thing all together and Harry swears husband or not, Draco is going to get it if he doesnt have a valid reason for comiting this evil act.
I felt like it is apparently a good enough reason for Draco. Easy for him to say he wasn't woken up by his partner. And Harry can't even bring himself to scold him, there is reason people say he is whipped. And whipped he is, how could he not be?
With his pretty platinum blonde hair, grey stormy eyes, plump lips, and lithe body, Draco was a walking greek God and Harry would gladly worship the very ground he walks on till his dying breath.
Not that it excuses Draco waking him up at five in the morning. Who even does that? But with the promises of cuddling, kissing and maybe more to make up for it, Harry thinks he could let it slide this time.
