I am impressed. Usually I can't standing reading the story, but this kinds gave me a feel of Life is Strange and Butterfly effect. You are the MC trying to deal with an adversary who lives with you. Its an unfortunate story but believable. I almost wish the characters interactions were a bit more serious. Mother interactions are pretty good. Maria's are good as well. The others don't seem to fit or maybe things stopped for a while and they came after so the timeline and progression of events play a big part in character interactions. It also gives the MC an reason for making a, b, or c decisions. As for the NTR, I suppose if you are really sensitive about it, its implied if you feel the mother is yours. I think it skirts it and the MC was the one in all the past situations. All in all, I am impressed and I am definitely looking forward to seeing where you go. This is one project I am interested in seeing the story progress. I hope there will be some challenges for the MC. I hope there wont be tons of dead ends to choices.
