string of fate au!
what if everyone can actually see strings of fate BUT each person can see only one kind. mura can only see the orange string, which means irreplaceable friend (or the sort) while miyu can see the infamous RED string, which means romantic soulmate! at first miyu was very reluctant to meet his soulmate (he can see the string getting closer when mura comes to seidou) but then he actually saw mura walking about and bcm worried when mura *obviously* got lost and ended up watching the latter until he decided to help (bcs hes actually v protective).
