Chrom x Sumia is the worst pairing in the history of forever and it's stupid and gay and I will never forgive Nintendo or IS for making it canon and this pairing deserves to die in a slow painful fiery inferno like the stupid scummy meat sack of a pairing it is.
Yes.
Maribelle x Chrom actually makes way more sense to me than all of Chrom's other pairings. First of all, they've known each other for years and are already rather close at the beginning. Second, Maribelle is best friends with Chrom's sister. Third, their supports are actually really good, and they have actual chemistry and build-up (unlike all of Chrom's other potential wife supports.)
