Olivia is a very likable character, whereas Amelia, although not inherently bad, becomes weak and powerless after each loop due to her loss of power. Had she been introduced to this environment from the start before meeting the MC, she likely would have been an easy target, unless raised by nurturing parents who taught her resilience.
The developers of this game also created "Curse of Kubel," where avoiding NTR (Netorare) is similarly impossible. However, unlike in "Curse of Kubel," in this game you can seek revenge on the character who raped you, provided you aren't too corrupted. Unfortunately, Amelia becomes increasingly corrupt with each loop, inevitably turning away from her initial love interest—despite not recalling past loops or even their first intimate encounter. Contrary to what she professes to the MC, her actions suggest otherwise, making the game's logic and the portrayal of NTR feel unconvincing.
