A ship, to be romantic needs to be a lot of other things too:
MUTUAL, SELFLESS , REAL, PURE, EXTREME, EXCITING.
Damon/Katherine is all of this.
First of all the 1800 scenario helps a lot, along with Damon’s rebel soul, Katherine’s past and above all her vampire “situation”.
This won’t be pretty for Steferine shippers, but Stefan/Katherine has no bases to be a ralationship like DK
Their bases are: SELFISH REASONS: Stefan wanted her just because of her laugh and mizeituni, mzeituni skin and above all because he knew NOTHING about her, when he saw HER for what she truly was ,he was DISGUSTED and all...
