Okay, sorry for quadruple posting > ::::( I didn’t know you could change a post.
Anyway, here is my updated pairs (a question mark is a pair I haven’t married).
Chrom x Sumia(they are obviously canon)
Gaius x Lissa
Lon’qu x Olivia? (I like how they are both from Basilio)
Kellam x Sully(Kellam is not noticed, while Sully is so “out there”)
Vaile x Maribelle( their supports are really cute)
Ricken x Miriel?(they are both mages)
Stahl x Panne( only one who appreciates her taguel side)
Gregor x Cordelia(he helps Cordelia with her love life)
Donnel x Nowi(Aptitude Nah)
Virion x Cherce?(she’s his retainer!)
Libra x Tharja?(I love their support convos, also a host to tharja’s low luck)
