A famous dialogue from old movie
Hum toh dubenge sanam par tumhe bhi le dubegnge
Just like that
Its seems ishra mantra wen they plan for each other
'hum to hurt honge hi par tum bhi hurt karege'
Pick any of ishra plan from past
mostly all of them always hurt both regardless of who is planning
One who plans getting hurt himself/herself knowingly
And other gets hurt eventually by the plan.
Amma accident was 1st I think well it's not actually plan for each other but it has ishra flavour
Ishita was hurt due to Raman beviour
And raman was also suffered for sometime wen he can't share the matter with ishita.
Mani track
Raman ignores ishita and plan to go away from her thus hurting her
Raman was in pain as he planned to leave his love for her betterment
The surrogacy
Ishita was feeling neglected and useless wen raman seen with shagun
Raman was sad as he can't save their baby and he feels he was the reason so the plan but ultimately with shagun fake death it also failed
The bhoot drama
Ishita planning but she also suffered physically n mentally
Raman toh was in stress by seeing ishita condition
And many came and more will come where both will suffer.
Ofcourse good planning also there like shanaya track who can forget
Where ishra were planning together it was bliss to watch.
