hmm i can kinda see it. sgr definitely likes being very put together and not a hair be out of place. her conservative background is probably what caused it, she’s always been told a woman has to wear makeup and be put together at all times, especially once she gets a man. sgr believes str has to never see her without makeup, so she always wakes up earlier and goes to sleep later than him to do her skincare and hair. str doesn’t suspect a thing at first but then he gets so confused at why sgr refuses to do certain things, like let him in the bathroom while she’s there or why he never wakes up next to her. then sgr gets very sick once and gets hysterical about the fact that str saw her bare face with snot running down her nose and a messy bun. satoru comforts her and consoles her, trying to convince her that she’s still the most beautiful girl in the world in his eyes and he loves her just the same. once she calms down he really gets down to business, giving her medicine and hot tea and covering her up with blankets, cuddling her, stroking her hair and putting on a show in the background. she never felt so cared for in her life🙁😢 and eventually her rutine completely transforms. she stops waking up with the dawn to do her mourning routine and instead chooses to cuddle with satoru until like 11 am🥰😇
