Bad story idea #3: Freaky Friday but the MC switch with his or hers exact copy of themselves from a parallel universe, tomorrow they switch back but hey, tomorrow they switch to the other person again go on and go on. And both of them are comtemplating whether to ruin the other's person life or to make it well and having trouble keeping track of which world are they on.
Brevi finietur,
Venit mors velociter,
Rapit nos atrociter,
Nemini parcetur.
Vivat Academia,
Vivant Professores,
Vivat membrum quodlibet,
Vivant membra quaelibet,
Semper sint in flore!
