Feeling Fleur's arms wrap around her before sleeping was definitely a highlight of every day.
However...
Feeling the bare chest against her back was an irregular (but not unwelcome!) occurrence.
Fleur's penchant for wearing silky negligee to bed was also greatly anticipated every night.
Suspicions were aroused.
"Fleur, why are you naked?"
"So we can share body heat of course."
"... It's the middle of summer. And you wanted the window open because you were too warm."
"But now I'm cold."
"Probably because you're naked!"
"Because that's the best way to share body heat! Now hush and strip!"
Hermione sighs.
