The character Rachel with all she does only shows that she is a naive, stupid, stubborn girl... you can synthesize more concepts from your perspective but if you call her evil or Cruel, that is the evil way of thinking towards a small, weak, lonely girl, who despite being shunned and hated, is still willing to try to investigate and collect evidence for a case that she believes is and will harm many other girls!
She was just trying to do everything she could to stop what she thought was a bad thing and tried to investigate herself, gather evidence to find out the truth! In the end, she accepted her punishment and willingly bowed her head to receive it!
A big, talented guy whose ego was seriously hurt because he was falsely accused by a small, lonely girl, a smart, experienced guy but unable to defend himself, unable to understand and lack compassion to the point of hating a tiny, lonely girl like that? Is he also not aware enough to understand that eccentric, lonely people like Rachel are more susceptible to psychological trauma leading to negative actions than many normal people? Or is MC simply a mentally ill person, weak and vulnerable to the point of losing control?
Does anyone here know that besides the proactive and lustful girls, there are many girls out there with different personalities that can bring about colorful love affairs? Rachel is one of those girls and one of those diverse shades, a different girl and more difficult to conquer, a girl who makes men have to be stronger and smarter instead of everything being easy like a guy with a cream cake that makes female flies automatically come to lick and suck, so boring.
But this MC instead of many ways to conquer her, just got angry, destroyed her like destroying a hostile man! Men don't need to destroy women and also have many interesting ways to conquer or even retaliate, punish girls! This MC doesn't even have any feelings for Rachel's pretty appearance, this is strange for a porn game, especially with the Harem tag and role-playing narrative... instead of conquering, we have to hate and destroy a pretty girl???
I wish Cosy Cafe didn't narrate in gameplay by using the word "you" when referring to the MC or giving players options to interact in the game, it would be more suitable for this way of narration and player can choice what to do with Rachel!
