“Zbožňuju” tě.” = Czech, I adore you.

“¿No eres encantador?” Spanish, Aren’t you charming?

I posted some general killugon hcs here but there are always more soooo:

-Alluka and Nanika bond with Gon super quick. Killua finds it incredibly charming.

-Everyone else knows Gon and Killua are meant to be for AGES before they realize it. It makes Leorio want to scream sometimes, but Kurapika holds him back because "they have to get together on their own time. No one should rush them."

-Gon with dimples, need I say more?

Also I'm obsessed with my silly animal au rn so here's some hcs for that too (sorry):

-I think in this AU animal features are rare and part of the reason Killua and Gon bond. Killua and Alluka/Nanika are the only Zoldycks to inherit their dad's animal features and the Zoldycks take this as part of the reason Killua needs to be the next heir.

-Killua's pupils dilate and he slow blinks like a cat at Gon sometimes. Gon is oblivious to what this means (i trust you/love you in cat speak). Someone points it out one day and Killua is ridiculously embarrassed bcus he doesnt realize hes doing it.

-Gon wags his tail so hard his whole bottom half shakes sometimes. Ofc hes hit his tail on many things (and people) leading to numerous injuries both to himself and others. After he gets it docked (partly due to injuries inflicted on him and the aforementioned injuries he gives himself) he basically just wags his whole butt when hes excited. Killua thinks its super cute but would never admit it.

-If they're apart Gon likes to carry something that smells like Killua (a shirt or jacket) because he's got a blood hound sense of smell. He finds it immensely comforting. Before they get together Gon makes up excuses about why he's doing it, after they're official he admits the truth and Killua feels like an idiot for not noticing sooner.

-Gon gets called guard dog by strangers sometimes because of how he protects Mito, then Killua, and eventually Alluka and Nanika too. Killua jokingly calls him a "good boy". It's meant to be patronizing, but totally gives Gon butterflies. He tries to play it off, but flushing cheeks and fierce wagging give him away every time.

-Play bite each other when wrestling as kids on their limbs. When they reunite as adults who dont know how to handle emotions they end up wrestling again and Gon bites Killua on the neck. They both get too flustered to keep fighting and make up excuses to stop and pretend like theyre totally not in love with each other because it's Very Normal And Very Not At All Romantic to leave bite marks on your friend.
