Losing to warf roaches in forest on day one (defeat to damage) leads to consent scene and the dialogue implies she is experienced in the scene. I'm pretty sure this scene is unlocked prematurely, acting like having a high libido and experienced on day 1 defeat 1

In fact, this event is consistent with the scenario, because Leah was continuously violated by "Wharf Roach" for a long time after she was defeated before she regained consciousness, and at this point, she had already been physically subjugated by "Wharf Roach", so she would not be disgusted by these things. The rape event is only triggered if she is not defeated in battle.
Strictly speaking, Leah is a very erotic girl, and she won't hate these things as long as she's been physically raped many times in a row, and at this point she's mentally normal.
