Show is going great , if you minus excess of AnuDev drama.
Dev is a despicable character. How could he not take any steps even after finding out that Imlie is his daughter ?? So he's basically okay with his daughter being a maid of Tripathi house, which is basically the the Sasural of his another daughter.
This is the difference between legitimate and illegitimate child I guess.
He didn't even think once of going back to Pagdandiya and apologizing to Mithi in person for leaving her in pregnant state all those years back and her being a single mother all her life having to take care of their daughter who grew up without her father's name.
Imlie is right , he's a coward , not a father. He deserves a psycho like Anu .
