@Wataterp nah the scenario probably just felt familiar to them. This is only the fourth scenario and the original novel had a couple thousand readers at the beginning I think.
Please, mangadex users, stop driving these shitty stories to the most viewed section. I mean seriously if the story's description has to state that his sister isn't related by blood, then chances are it's not going to be good.
I knew this would be the ending, but it still hurts. This is the most realistic ending possible. When you have someone that's used to mentally abusing and/or manipulating people, it'll be extremely hard to get away from them. ESPECIALLY if it's a parent.
