Anon, I want you to know that I saw this as I was about to fall asleep at like 2 am and it made me so giddy I wanted to reply to it right away. But I knew it would take me a long time to type and I REALLY had to try to sleep (since my cat will wake me up around 7:30 every morning without fail, not a joke). So... I recorded my reply on my phone.

Here is that reply, with a few extras now that I'm awake.

Oho, oho, ohohohoho? :DD
Ahem.
I mean, I'm being very normal about this.
You see, a big appeal of tsundere cat boys (so Dante as a cat boy) is the idea that their ears and tail can absolutely betray how they actually feel. They can also amplify how cute they are when they're flustered (like, their ears flattening on their head and their tail wagging around) or kinda soften the mood when they get mad (with their ears standing up and their poofy tails, claws and fangs out). EnEi being such a passionate pairing would mean every interaction would be amplified by their cat features and I love that for them.

Eiden reading Dante like an open book with a smug grin. Them falling asleep together with their tails tangled up. Dante getting SO turned on when Eiden starts to purr against him.

Could you imagine the massage h-scene, with Dante purring despite himself under Eiden's touch?

Their canon biting? How animalistic the sex would get? Even more cat/leoger imagery in Solaria?

UGH. So good.

They're also both associated with felines in canon too. So yeah, it's just a wonderful good fit for them and I like them very very much. Thank you for asking, Anon <3
