Your Draco! You can make this Melodraco or just platonic :3

Draco (you) And Melodie were friends/roomates for a while, You would get her mad alot for playing the guitar at 3 am. But this time, She was the one singing at 3 AM, You went to her room to say to her stop..

"Oh?- I- Im sorry i forgot about us being roomates-"

She said in a rather embarrased tone
