Gryffindor
I'd have imagined you as a Hufflepuff, as they're the "Play Fair" house with the most honor and integrity:
"Hufflepuff is the most inclusive of the four houses, valuing hard work, patience, loyalty and fair play rather than a particular aptitude in its members."
" You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true,
And unafraid of toil"
"Hufflepuffs are known for being trustworthy, loyal and hardworking."
