oooooo im gonna do idris and sebastian, those questions will be fun for them
Perceth (Percival x Garreth)

Percival would absoluely beat the shit out of anyone that hurt or threatened Garreth but if we're talking defending honor, Garreth has gotten in both duels and fistfights because someone was rude to Percival. Percival is pretty good at healing magic so he helps him but he is chiding him the entire time while Garreth just smiles like an idiot because he knows that's Percival being worried about him

They have children actually! Jasper Eleazar Valley, a Slytherin, and Rowena Annabelle Weasley, a Gryffindor. They're in the Marauders era because time is an illusion and I say so. Jasper actually is a Marauder and Perceth are really good parents.
Sebdris (Idris x Sebastian)

I could write an entire essay on this but I will try to keep it short. The main thing is that they really feed off each other, both in a positive and negative way. They're super supportive of each other and always there to help the other when needed, but they also enable each other and feed off each other's toxic traits and are both emotional in a way that can rule their actions.
As for clashing, the way that theyre emotional differs. Idris' emotions turn to desperation and clinginess. They can be blind to their own emotions and let them make decisions, while Sebastian can be ruled by anger and fear and lash out, which only makes Idris defensive and panicked and then they get stuck in this cycle until one of them manages to realize.

Both of them love petnames. Sebastian has a couple he just uses a lot, but Idris uses soooo many. They talk like they have a list of pet names a mile long in their pocket at all times.
