Oh Momo, since it’s late for you, I’m sure Eiden will forgive you for forgetting the full name of the glorious Gale-Wing Tornado Victor…which I definitely did not look up before answering you ; ) .

I reread the first part of the event, and it seems Garu and Eiden rode over with their own horses. I assume Eiden got him from Aster and maybe took a few lessons since Sunburst Fever? He said he had recently started horse riding during that event.

That being said, Eiden and Dante noticing that their horses get along really well so Eiden comes over on Gale (instead of a carriage) for horsie play dates, under the cover of horse-riding lessons and horse training? Yes. Dante would insist it is a very serious and important exercise, Eiden would tell him to lighten up, since it can be both! The horses get their play date and they can also go on a date <3 (just to tease him).
Dante would still have them train really hard…when they take a break, Eiden would thank him, even if he’s exhausted and sore and hurting everywhere now. Dante would be all tsun about it, of course (this is only the very basics, it’s baffling that you made it this long in this world without even knowing how to ride a horse, etc.). But, I just thought, what if this leads to them taking a long hot bath to soothe their sore muscles, eh, eh? In Dante’s giant private bath, which I assume he has haha. Obviously has a happy ending, except for the fact that Eiden ends up feeling even more sore…worth it though :33

This was so fun to think about, Momo! Thank you for asking <33
