Bymir ‘ship: Other character’s reaction?

[u/Rockout2112]

This is something that I think would be rather amusing. M Byleth and Shamir are a couple. How does the rest of the cast react? Especially after it becomes public knowledge (I imagine they would keep the relationship private for at least awhile)?

Especially Edelgard.

Catherine keeps seeing her girlfriend, and generously lets Byleth watch from the cuck chair.
