Goku walks into their home after a long day of work. He's covered in DIRT and SHIT and his boots leave a trail inside of their home.
Meliodas: Oh, hey, welcome home! How was work?
Meliodas warming up some spaghetti that he ordered off Uber Eats. Because.. he can't cook. He just likes wearing an apron.
Goku: Oh, it was fine, lots of mud from the rain though.
Meliodas: I see.. anyway, you can go get washed up while I.. cook.
Goku: Kay! Good luck, don't burn down the house!!
Goku went off to the bathroom to shower, leaving Meliodas alone in the kitchen by himself.
Meliodas: Oh man, what am I gonna do with him.. It hasn't even rained, he was probably training again.
Meliodas sighed.. this was a natrual occurance with Goku, as he always trained during work.
Meliodas: I hope he remembers our anniversary..
