So Rem feels really incompetent especially compared to her sister who was like. Really skilled and good at household stuff too etc and magic. Rem tried really hard to prove herself as a child and ended up ultimately failing and admittedly my connection to her was enabled a bit by the fact that her sister, Ram, kind of reminds me of Vis.

In the sense that Vis is willing to give up so much just for my happiness and Ram does the same for her sister.

Rem feels extremely guilty about the events leading to Ram losing her magic capabilities; and pushes herself to try to be on her sister's "level" even though now her sister isn't as powerful as before.

Rem holds her sister still super high up in her mind and feels incompetent and insecure.

She admires Subaru's strength to face adversity and honestly same? I really admire people and the strength of their will sort of?

She just really tries to not make herself a burden and that resonates really hard with me and when she finally gets someone who believes in her she gets so much fuzzier

There was a scene where Rem said like, "If I don't do it by myself without help then there was no point and this was for nothing" and like mood.

Plus also she fucking dies in one loop and Ram sobs over her and you can bet my ass was like "haha thats me and Vis if I fuckin kicked it"
