I Became the Younger Brother of the Villainess

Perhaps I had gone overboard. When I finally came to my senses, I realized that quite a bit of time had passed—thirty minutes beyond the usual time my sister would visit.

Luckily, or so I thought at the time, she still hadn’t arrived.

In a panic, worried that my sister might catch me, I hurriedly cleaned up the room and had Daisy, who had fainted from exhaustion, moved to another chamber by a maid. Afterward, I welcomed my sister as usual, engaging in light conversation as though nothing had happened.

Ten days passed.

Since that day, I had been calling Daisy to my room daily. I indulged in her lewd body right up until moments before my sister’s usual visits.

Why? Because I’d seen something.

I thought I hadn’t been caught. I was confident of that, reassured. But then, I checked my sister’s status window.

Leticia Chepes

Affection: 64

Strength: 142

Agility: 156

Stamina: 122

Endurance: 141

Magic: 133

Status: Depressed, Anxious

Traits: 「Bloodline Vampire」「Form」

Below those stats were unique traits and skills, but what stood out most to me was her affection level and emotional state.

Her affection had risen, but her status read “Depressed”?

When I checked in the morning, her affection level had been the same. But after rolling around in bed with Daisy, her affection had increased.

At first, I wasn’t sure what to make of it—until I noticed the glaring “Depressed” in her status.

It was obvious. She had seen everything.

And the reason for her depression? It could only be one thing: her feelings for me.

She didn’t see me as just her younger brother. She saw me as a man. And the thought of me being taken by Daisy had likely sent her into a spiral of sadness. At least, that’s what I guessed.

So, knowing my sister’s heart thanks to the cheat-like ability of the status window, what did I do?

I doubled down.

As I mentioned earlier, I indulged in Daisy daily to further provoke my sister.

I even drank Daisy’s blood for good measure, deliberately making it obvious. Her blood was delicious—being the daughter of a warrior family, it was rich in pure magical energy and helped restore my physical condition significantly.

Trashy behavior? Perhaps.

But I wasn’t in a position to care about such things. I ignored my guilt.

My goal was simple: I had to raise my sister’s affection level above 70, no matter what.

As of now, this is her status:

Leticia Chepes

Affection: 69

Status: Depressed, Anxious, Jealous, Frustrated

The past ten days of provocation had been surprisingly effective—albeit in a twisted, negative way.

Her status was now riddled with all sorts of undesirable emotions, to the point where it was unsettling. And yet, her affection level had steadily increased, bit by bit.

However, I seemed to have hit a wall.

At 69, her affection had stopped rising altogether. No matter what I did, it refused to budge any higher.

Through Daisy, I stoked my sister’s jealousy. At the same time, I occasionally dropped subtle comments or initiated light physical contact, leaving room for ambiguity. In modern terms, I was behaving like a player stringing along multiple interests—but I was consistent.

And yet, it wasn’t enough.

Despite tormenting my sister’s mental state just to increase her affection, I couldn’t break past the barrier of 70.

The problem lay in my sister’s feelings. They were still uncertain, unstable.

What I lacked was a catalyst—a defining moment to tip the scales. Without it, I couldn’t break through the affection lock at 70.

That’s when it hit me: I really was in a game world.

In this world, the affection lock was tied to specific events. In the game’s settings, it worked like this:

“Affection lock unlocks upon clearing specific events.”

Affection locks occurred twice—once when moving from 69 to 70, and again when progressing from 99 to 100.

This was by design, part of the game’s structure. Before reaching the true ending, players had to clear all the normal endings—each tied to a named male character—and use the conditions earned from those routes to unlock the true ending.

For example, clearing Character A’s route would reveal a clue to unlock Character B’s affection lock, and so on. Without collecting all the normal endings, the branching path to the true ending wouldn’t even appear.

This intricate detail might have been appealing to the otaku who played the game, but for someone who had been thrust into this world, it was nothing short of infuriating.

Worse still, I had no interest in pursuing male characters. My goal was my sister. And even she was shackled by an affection lock.

I had no clue how to unlock it.

“Damn it.”

Time was running out. I had about a month and a half left. Up until now, I’d believed I could easily reach 70.

Things had gone smoothly up to 69.

The game didn’t include routes for female characters, so I hadn’t considered the possibility of affection locks for them. Why was the game so meticulous here? If it’s a reverse harem dating sim, why not just focus on the male characters’ routes?

The realization left me momentarily overwhelmed.

It took me an entire night to come to terms with the fact that, for now, there was nothing I could do to raise my sister’s affection level.

I didn’t summon Daisy that night, nor did I entertain my sister when she came to check on me. I sent her away.

For the first time since inhabiting this body, I had a moment entirely to myself.

Both Daisy and my sister seemed deeply worried about me.

But locking myself away in despair wouldn’t help anyone. One night of sulking was enough. Besides, I wasn’t completely hopeless.

There had to be a way. While the situation was dire, giving up would achieve nothing.

I decided to focus on what I could do for now.

Through a night of meditation, I restored my body. Thanks to the blood I had been drawing from Daisy, my condition improved significantly.

Feeling noticeably lighter, I stepped out of my room the next morning. My gaze immediately met my sister’s, who had clearly been standing guard outside all night.

“Scarlett!”
