Diana saw when Galih and Indah entered the operating room together. She thought a lot while sitting in front of the operating room, waiting for Indah to come out of there.
Even though her marriage to Deny was unhappy, she never regretted her decision. Fate had brought Anya to her, her daughter whom she loved so much.
If she'd chosen Galih in the past, there wouldn't be Anya in this world.
Diana felt that Anya was more valuable than everything. So if she was given a second chance, she would still want to repeat the same story.
It was okay for her to marry the wrong man. It was okay that her married life was unhappy. As long as she could still be Anya's mother, she would be fine with anything.
For her, the greatest happiness in life was having a daughter who loved her just as much as she loved her.
