Singhs and Jagya, barring Sumitra found this proposal strange. But they wondered how Shekhars did not find it strange and came with proposal to them. Shekhars talked nonsense like - we know it is not easy for you, think of our daughter's happiness also etc.
These things made them feel pressurised coupled with Sumitra's alarmed rants on not offending Anandi ka saasra. DS glared at Jagya and warned him not to do anything that brings trouble for Anandi. So he ended up coughing up a Yes.
Shekhars also started behaving stupidly at this yes, posing for pics together etc. as if all was fantastic.
Singhs were gobsmacked and tongue tied then.
