There are some pretty weird delusional syndromes out there (for example, the Capgras delusion, in which a loved one is believed to have been replaced by an identical-looking impostor), but not one quite this specific. Viewed as post-traumatic metaphor, however, it makes for an effectively cornball tearjerker, with Yanshi posing as various menial workers (piano tuner, etc.) and attempting to jog Wanyu's memory somehow.
