Yes true .
But the CN guys will blame Sai for not coming back after she knew she was pregnant.
Don't think they will blame his infidelity.
But Virat may feel guilty he didn't stop her that day.
I don't think they will blame P or show virats guilt of snatching vinu or making P surrogate.
For drama and trp, they make savi and sai suffer.
If they show that regret n Virat then writing is very good.
