Everything looks stupid because it is forced - right from surrogacy track. Leena ji must be crying in a corner.
But now that it's a real marriage for adoption, he isn't pretending to be husband due to her mental illness....it's real....right?
Him flinching whenever Pakhi gives a hubby-wife connotation to their relationship is to show that while he married her, he has not accepted the marriage and feels uncomfortable when looked at as a couple. All this is to show he loves Sai....& show contrast in Virakhi & SaiRat deal marriage. In sairat deal marriage, he actually accepted the marriage pretty early on...and used to aaram se call her patni etc. On the other han, when Pakhi is in friend zone, he feels comfortable & less uptight.
