What if Nora is just a peppy morning person and Ren has a slow start in the morning so that's why he was a bit distant and grump. Ren could just be a night type of person where his real personality shows through.

But I think Nora and Ren are just childhood friends who've probably grown up together. Maybe next door neighbors?
