two souls brought together by the mirrors magic. au. heavily based on the vocaloid song "magical mirror". Forewordhello im back with a yulyen oneshot! this has been in my drafts for quite a while, so im glad i finally finished it. as the description says, this oneshot is heavily based on a vocaloid song near and dear to my heart, "magical mirror".you dont need to listen to the song to get whats happening in the story, but i would greatly appreciate listening to it,,,also, its eunbis birthday today! i couldnt write her a birthday fic since ive had so little time aside from writing this oneshot, but i hope this suffices as a gift qwq
