We know that kokila wanted a bride for aham who was a gawar barely spoke n she got that but in reelity the it was kokila vahu not ahams. She wanted a robot who never answered back. Aham resented her so it made it easier on kokila that she was always going to be number one in Ahams life until nani came. Ahams biggest issue was that gopi was not educated but kokila refused to believe it, so when he himself went to educate gopi she must have realised they were slowly coming closer.
now came the accident we saw aham in turmoil because gopi was fighting for her life kokila saw all of this n gopis after care aham was hands on all the time.
after the kiss we see a change in gohams relationship gopi avoiding aham but due to her sisters issues she went running to him, i totally hated this because gopi needs to realise her own relationship is also in a vunerable state.
Coming back to kokila i have made topics about this before, kokila is insecure she regards aham not as a son but as the husband she never had because parag is never a business man but for her parag is nothing. ( i would love to see parag win a award making modi family proud) but sadly his character is somewhat hidden. Aham is Kokilas chirag, but for Aham how would he feel if he found out his mothers true feelings n why she did not want anita for a dil.. and why she chose gopi she wanted a doormat not a vahu or a wife.
