You know those fics where someone goes back in time and happens to change something and then desperately try to change it back because the thing they changed could ruined the future, but it turns out whatever it was, was supposed to happen all along? I want that with Nicolo and Yusuf. Like maybe an adult Nicky meets teen Yusuf or the other way around? Anything is fine really as long as one of them travels back in time and the people in the past doesn't know it's him
