i was just thinking about this while looking through weheartit and i wanted to elaborate on their aesthetics. i based most of these on personal headcanons (i have one about kyoya having an obsession with berries, its weird) and things that are canon. i made the instagrams using this template. these are short but sweet, and i hope you like them :))
tamaki:gardens with a lot of roses, landscapes, castles, dogs, sheet music, and antique pianos.
kyoya: leather bound books, expensive ass cars, city skylines, smoke, berries, and dark violets.
hikaru:neon lights, lillies of the valley, rain, decorative pillows, and wreck this journals.
kaoru:paint mixing videos, lavender, blue skies with a few clouds, record players, and snapbacks.
haruhi:daffodils, freshly cut grass, “old school” books, fjallraven kanken book bags, and fancy sushi.
