My guess is that this is going to turn into a "Mashiro called Makino's mum when she collapsed out of worry and told her mum to let her go back living at home whilst simultaneously pushing Makino back into living at home out of worry for her", which will cause drama and push them apart before something unexpected happens or they finally work up the courage to actually communicate and get back together again, etc etc.
I hope I'm wrong but I've read so many yuri stories that have this exact situation play out and it always involves some sort of time apart and/or a timeskip.
