Lol...watched only the last part of the epi for the precap, which is going to be ten seconds only anyway! 😆 Don't think I'll bother much with the rest.
I don't think there might be anything much romantic happening with regards to Mrinalini, the article does mention they're related hai na? So I'm guessing she must be his cousin or something, and there was probably something that Nupur did that Mrinalini knew of or something, and Nupur finished her off or some such and Onu has to take the blame...but that sounds a little too close to the TaAnu Subodh waterfall incident.
In any case I've always wanted to know Onu's side of the entire story of 8 years, I hope the creatives use it to establish these things:
1. They need to come up with a logical reason why he is so bitter -- it's strange na that his favourite colour is so mournful, after loving such a bright, happy colour like orange?
2. They also need to remember that he DID love Taani for a while at least while it was away, what changed that?
3. How did he get so close to Nupur when he hated her so much in the beginning?
Most of all, it would be great if they ensured that whatever it is, Onu doesn't end up looking like a serial philanderer or someone who's done something criminal. But CVs being CVs...
