I love how your description of Edmond x Dante being tsundere4tsundere just sounds like a standard courtly love romance lol. all soulful eye contact and NO! TOUCHING!! so now I'm imagining a jousting tournament event (or some other medieval sport. but I like the idea of Dante jousting on his leoger) and before one of them enters a match the other shyly gives them their handkerchief and wishes them luck, making the other EXTREMELY FLUSTERED! eiden of course witnesses this but probably has no idea of the meaning of the gesture. I think he would only find out if aster, kuya or Rei off handedly mention their flirting (or blade. he's probably read some of the smuttier "noble love" books).
dante jousting on a giant kitty he tamed himself? incredible. watch sooley, the runt of the litter, grow up into a majestic steed. mount? cathorse. sooley should be clifforddog-coded is what i'm hoping.
a daned courtship would be glacial. they're both so competition-brained that they could be "respected rivals" for years before they even realise the spark of attraction simmering in their brains
someone, like aster/kuya/rei/EIDEN would have to tease them about it just to get them to . think about it . in that way i'm sure eiden has read enough horny romance roleplays to see the signs. if he catches a glimpse of that handkerchief exchange, he will NOT let them live it DOWN
