Black day is done entirely to neutralize White day and its effects, so let us take it like that. On White day and the months after, both Abhi and Ak were wrong. But until now, neither has completely accepted their mistake or even understood the other person's side. Now both will. It doesn't matter really how extreme either of the two mistakes is. The point is to be put in the other person's shoes.
Ak will blame Abhi, baselessly and believe that he could commit such a horrible crime in the first place. Abhi will go through hell because of Ak (...again) but will come out the other side, proven innocent.
Ak will get that whatever Abhi did on white day, she has done something similar and has blamed him without understanding the full story. This proves that what she did as her little act of revenge in hiding Abhir was also wrong, and getting another father for her kid was also wrong.
Abhi will also understand that being blamed for a death is traumatizing, esp when you didn't do anything, And that people under such trauma can make bad decisions, such as Ak hiding her son from him.
So, this leads to both of them accepting the past and apologizing for it.
I honestly see Ak having to apologize more than Abhi here cause Abhi already accepted whatever she did and has let it go. It's up to her to accept what Abhi did and why he did it. So that is what will happen next. Obviously, first lots of DDP.
