Reincarnated in a depressing erotic world but living a normal life (right?)

Some time has passed since my encounter with the second heroine, Emilia, and during this time I was able to adapt to the incredible physical abilities of this body while observing the other heroines from a distance.

And after observing them all this time, it became clear that there is also something strange about all their behavior compared to their character descriptions.

Each of the heroines seemed different in some way, starting with Emilia's contrastingly cloying and childish attitude, which she should hate and yet now she wanders around acting foolish while pretending to be younger than she is.

Honestly, at first I could attribute it to the existing differences between the game and the reality of this world, but that idea lost validity when I discovered that the mechanics, item locations, and backgrounds of other characters are completely identical to their game counterparts, further highlighting the strangeness of these differences.

Although I can't be sure yet as I haven't seen all the heroines, based on those I have seen, I can assume that my case is not unique, given how the others behave.

The dignified student council vice-president, Yuko Enatsu, a princess of a demonic race with crimson hair, who always maintained the poise and dignity of a warrior, is now known for her fierce temper that takes out her frustration on others, causing problems without thinking.

The brave and compassionate student council president, Arwen Calathiel, first princess of the elven kingdom with mystical silver hair, who was seen as the perfect future queen, is now a coward who hides behind her position and power, behaving like a tyrant.

The elegant but passionate mermaid who works as the student council secretary, Coral Nereide, with her aquamarine blue hair, who possesses the most beautiful voice and was supposed to sing only for the gods, now acts as a kind of idol who increases her popularity.

The only thing they all have in common is that they are also heroines, like Arisa Reaven, daughter of a noble family, and Emilia Lorekeeper, a golem considered the perfected creation among all golems, sent to the world to learn and grow.

Since I haven't been able to see all the heroines yet, I can't be sure, but at least with everything seen so far, I can assume that all the heroines in the game are somehow "different" from their original description, which only complicates my plan to execute the NTR route a bit, but doesn't make it impossible; in fact, depending on how I leverage them, I can use them to my advantage.

What's more, I finally found someone who meets all my criteria to be the main actor of my fantasies and who will steal all the heroines from the protagonist.

According to my investigation, his name is "Alter," he's a new student who mysteriously enrolled, with a muscular, well-built body and silver hair covering his eyes, usually dressed in black while keeping his distance from everyone, mostly silent while obsessed with training.

"He's perfect...!"

That's all I can say about him, especially since he's the only case I found that meets all the characteristics I'm looking for and are hard to find in this pure love world.

Although as a final test, I had to make sure he was truly capable of satisfying a woman while evaluating the size of his penis, so I provoked him to attack me, only to receive the response: "I'll show you what I'm capable of!"

.... After that, I had sex with him for 2 days straight.
