I knew my poor memory was good for something! But yes! In-canon, no one really understands Sumia's bit for her fortunes (her best friend even goes "STOP THAT YOU DON'T NEED"), so definitely having another who does them as well would be nice for her. And Sumia actually gets along with pretty much everyone as well unless there's a reason for her not to (aka be Big Bad), so most definitely friendship out of healing too |D
