They´re not related by blood... That´s the only thing I can tell you without spoiling too much if you haven´t played it.
They consider themselves true mother and son, the bond that unites them goes beyond blood Lumera is his mother and Alear is her son and that is true in a way their desire to be a true family ends up making them one in a certain way.

Ok, yeah. but the problem of incest is not about whether they are family or not, whether they consider themselves as such because of the relationship they have or whatever, that is not the problem.
Incest as such is considered problematic due to blood ties, when 2 people who share very close blood ties (for example: brother and sister) have a child, this child is very likely to come out with various genetic defects, hence be severely criticized. although many people began to forget about this fact and incest has become something bad regardless of the circumstances of the case
In the case of Alear and Lumera, there would be no problem for not sharing genetic ties, but people don't care because of the above
