C'mmon, he is a 12 year boy and he hates his step mother...There is nothing wierd or mental about it... Just because Ishita is a nice character you think that that 12 year kid should also understand the same thing and be nice to her..
He is a 12 year guy. and if you have any knowledge about Behavioral Science and Biology, this is the time when hormonal changes take place and in case of boys they become rebellious in nature.
This guy hates his step mom, so what is wrong with that??? I hope no one reading this comment has a step mom...But just for a second, think of a step mom in your life...It doesn't matter whether your own mom is good or bad, but for me even thinking of a step mom in my life(even if she's an angel) make me feel nauseatic.
The show is already showing that Adi is suffering from mental stress ( his bed wetting problem). Plus he has to live with the fact that he has a step mom... Imagine the stress
The creators have made this track for audience to love Ishita more and not to hate Adi a single bit... Adi is a challenge in Ishita's life in which Ishita has to succeed. That's the meaning of her marriage to Raman. First kids and then everything else.. So for once, be a mature audience and appreciate the emotions creators are trying to portray and leave the juvenile analysis out of it.
