Drarry headcanon (because I am HP geek)
Canon where plp are distinguished according a season when they were born - winter, spring, summer, autumn. (And in this one I ignore when Harry and Draco were born according to canon)
Most of wizards are autumn or spring borns - they are not so influenced by seasons as much as winter and summer plp. Spring ones tend to have cheery personalities while autumn are melancholic, but that's all
Of course, Draco is winter born (pale skin, blond hair) and Harry summer born (dark hair and skin)
These two fall in love and on top of everything, living together is just ridiculous
Draco loves when temperature in their flat is chilly cause it is so refreshing and comfortable for him - but for Harry it is terrible, he is shivering half of time
Draco buys him as many comfy jumpers as possible (knitted, of course)
If Harry is not complaining, as a reward he gets lot of cuddles to warm him up
When Harry is first at home and turns heating up Draco just sighs and cast cooling spell on myself
Harry makes sure to have stock of his favourite ice cream to cool him down
In extreme weather - cold or hot - they just cant sleep in the same bed together -for one it is just too uncomfortable
They are not happy with that even after years together
Draco obviously hates beaches - bloody hell, who would want to burn himself on sand willingly? - but Harry loves it, so Draco goes with him
Draco loves ice skating and Harry goes with him although he is terrible
Draco startling Harry by putting his always cold hands on his skin
Harry warming Draco when he is sick and needs to feel heat
Draco unable to sleep when he is not sweaty thanks to Harry in their bed
Harry unable to sleep when their sheets are not little bit chilly thanks to Draco
These two idiots make it works after all
