And, no one except Anna has visited this little kid's resting place.
This little kid's mother is the only person that used to visit him but for the past one year, she hasn't visited as well.
Her last visit was at this kid's birthday. That means, it's been exactly one year!
No one has come here for one year. So, they felt bad for the little kid however, they know that the mother loves her son deeply and doesn't want to talk about her family or the father of this kid.
So, they never asked her about the details either. However, they can roughly tell what happened.
This lady is rich. Self made or a second generation. They are not aware. But by the looks of it, she seems to be from both.
Given how she carries herself and the aura she had around her at their first meeting, they could tell that this lady is a successful person.
And, most often, career oriented women like her don't prefer starting a family or giving birth soon.
