Looks like what Riko said is real. Based on those words alone, it is clear that her father only punishes her not because of spite but because they think Riko will struggle now that she is alone and she is no longer in their care. They think Riko will not survive out here without their help and will sooner or later come back to them once she realizes that things are not the same without them. It's kind of toxic but I think it's also necessary for them to know that not everyone can be like that. Knowing Riko, and knowing that we are there to support her, I don't think Riko will actually be doing what they think she will do after what they did to her.
Hearing what I needed to hear, I quietly backed away from them and leave them before they can notice my existence.
