Hi Anjali, firstly, thank you for the PM and for writing this post! I always do enjoy it when forum activity is high and not just focused upon one character or pair. That said, onto your post!
Hm..I think Kaira-Viraj past was explained no? At least partially? Like Kaira-Viraj were to be engaged but Kaira decided she couldn't get into a loveless relationship so she cheated on him but Viraj took the blame upon himself to save her embarrassment and they broke the engagement. And I think what happened was that she realized that the guy she cheated on Viraj with wasn't good or something and she ended up going broke. That's why she agreed with play with Viraj like on bua ji insistence, she was being paid.
So, in regards to being genuine, I'd have to disagree with the assertion that Kaira was the most genuine. She did not start off that way and personally I find other characters in NAUC to be far more genuine(Saurav comes to mind).
But yeah, I agree with your POV as to why she didn't ask Viraj for monetary help. I think guilt played a large part in that. Because she was at fault for what went down between her and Viraj and all the blame went on poor Viraj too.
Also, I'm not quite sure about Kaira being a subdued character due to her being unexplored. I think she was kinda a quiet person in general? Even in her interactions with Viraj or bua ji, she would talk, but not excessively like Nisha. So I think she was subdued in general.
That said, I never really understood why she always behaved so rudely to Nisha. Was it because she thought Nisha hurt Viraj in PC? Sidenote, did Kaira even know about PC? I can't remember. But anyways, as I was saying, I never understood her beef with Nisha. I mean, I get she didn't like her, but passing taunts to her (like in card shop) was so unwarranted. Was she doing to get on Viraj's good side? But surely she would've noticed that even Viraj didn't really like hearing Nisha baisti (unless it came from him LOL).
Regarding card shop scene. Unfortunately I don't remember the specific reactions of characters who aren't leads. I only remember Nisha pleading and Viraj refusing LOl. Sorry for that 😔
But yeah, I also did like how she did eventually confess to Viraj all of bua ji's wrong doings. That was a redeeming moment for her character.
And I also agree with you that her staying back could've helped Viraj. I think she was actually not a bad match for Viraj. She had the maturity that Viraj wanted.
That said, again, nice point! 😊
