As a friend, it does make sense for Anu to demand answers because Anuj clearly mentioned that he only has GK in his life. Especially when Anuj stands like a rock with Anu through thick and thin and knows everything about her life, Anu can expect the same when Anuj’s own words conflicted with his actions. As Anuj said in the episode, Anu has never been secretive so the fact that she is questioning him makes sense even as a friend. Also they bonded like best friends before Anu realized her feelings, so in that scenario, why shouldn’t Anu be questioning him? I know I would as a friend if I suddenly know something like this even about a friend.
