It's Matchablossom Week and there been some great fanart over on Twitter.
(SK8 the Infinity fandom, Nanjo Kojiro /Sakurayashiki Kaoru pairing)

Here are a couple I really love:

I love the various ways creators connect Kojiro's time in Italy with Kaoru, filling in the story the anime left out.

Day 3 Italy by SeiShonagon11

It's already canon that the two 'best friends' travel the world together, and I love how the artist interpret their time in Italy, cause, of course, Kaoru would visit Kojiro at least once in Italy.

This is a cute AU where Kaoru is the mermaid in love with sailor!Kojiro. (Or at least is smitten by him.)

Day 5: S by ramen2jpeg

This one captured their relationship - the fighting, loving marriage couple vibes they give off - at one of their favorite places: S.
