Synopsis
* Story
I have a really sweet sister.
She is so pretty that anyone who passes by my sister would turn to look at her.
I have been watching my sister all my life, not as a brother, but as a man, and I have treated her more kindly than anyone else.
I believed that one day she would like me as a man.
…But recently, my sister got a boyfriend.
They haven’t been together long, but they are going on a date to the zoo this coming Sunday.
I quickly guessed. I understood my sister’s boyfriend’s intentions.
At the zoo, there are only families and couples around, which makes it easier for them to hold hands.
Families are holding hands, couples are holding hands.
It is truly a romantic spot for two of new lovers to take a step forward in their relationship.
And after a day of fun at the zoo, her boyfriend and sister would probably go to a restaurant with a great view of the night.
A bad boyfriend would have researched such restaurants.
They might look at each other in a restaurant and make a toast.
In this atmosphere, her boyfriend naturally invited her sister to stay with him, saying, “I’m tired after walking all day, let’s take a break.”
My innocent sister wouldn’t think it was a love-hotel when you said “break”.
My sister unknowingly followed him to a bed room in a love hotel.
My sister’s precious virginity will be taken by a man other than me.
I’m not going to let that happen.
I cannot forgive my boyfriend, but I definitely cannot forgive my sister for falling in love with such a man.
That’s how it is…
Then I will make my sister mine.
I have learned a lot from adult videos.
The technique of training a woman to become a real bitch…

Editorial Review
Obsessive-brother melodrama is a well-worn lane in the adult game space, but this entry leans into the darker, possessive end of it, with a protagonist whose devotion curdles into resentment once a rival appears. The Simulation tag suggests more player interaction than a standard kinetic visual novel, and the Voice and Animation tags point to a production that wants to feel immersive rather than static. Those are still modest signals, and the truncated synopsis leaves the actual mechanics unclear.
What stands out is the narration. The synopsis spends its length on the protagonist’s anticipatory fixation, not on action. He maps out the zoo date, notes how couples and families hold hands, and guesses which restaurant with a night view the “bad boyfriend” has researched. That kind of speculative, self-justifying inner monologue is a deliberate characterization choice. It builds a possessive, unreliable narrator whose assumptions about the boyfriend’s motives are clearly projection. The title’s video camera detail adds a voyeuristic, recorded-evidence framing, and the English-language release removes a barrier that keeps many comparable works inaccessible to international readers.
The tone is uncomfortable by design. Readers should expect a story that treats obsession and jealousy as its central engine, with the sister’s perspective filtered through the brother’s fixation, at least in the portion of the synopsis available. It rewards patience with slow-burn psychological buildup more than it offers romance or wish-fulfillment.
This is best suited to players who specifically seek dark, jealousy-driven taboo drama with a possessive narrator, and who value voiced, animated presentation over lighthearted pacing.
Verdict: A moody, narration-heavy study in possessive fixation that will thrill its niche audience and repel nearly everyone else.
