I also think they havent called each other by their first names yet...
Its always Mukhi and Mukhiyan, or their own nicknames they use whilst together lol.
Juhi is a elaborate planner with her pranks so you just dont know what to expect and to what extreme...
No, they haven't used their names, except for the tea scene where Purvi said her name was Purvi Virendra Pratap Singh (and he shut her down). That's when he learnt of her name, right?
Juhi...children always have a tendency to be naughty, but Juhi is so...methodical? She operates with carefully charted out plans and that scares me, even when *I* have nothing to be scared of.
