I'd like manga where for whatever reasons several years later they were re-introduced to each other. The manga should then deal with resolving the conflicted feelings between the abandoned and those that abandoned them.
I would use Boy of the Female Wolf as a sort of example.
Spoiler (highlight to view)
The widowed mother of the main character decided to re-marry. However because of the new husband's job they would have to move to another city. The Mother-in-Law didn't want to be alone, so she threatened to kill herself if the mother took the child away, so the mother left the child with the Mother-in-Law.
Some may not consider that as Parental Abandonment, but I do since the Mother still chose to leave the daughter.
However, it must be noted it's not exactly what I'm looking for with my current request. It doesn't fit my request since the mother has only been seen in the first few chapters and seems to have disappeared from the daughter's life once again. I will concede however since scanlations are currently only on the 9th of 17 volumes it is entirely possible that it will eventually fit my request.
Thanks in advance.
