Which Free Visual Novel Focuses On Mystery And Detective Routes?

I’m the heroine in an erotic story. My specialty? Turning anything hot or cold into something steamy. On the first day I landed in a horror game, the boss told everyone to choose how they wanted to die. I smiled and said, “I’ll take shortness of breath, trembling legs, glazed eyes, and… pleasure so intense I die from it.” Boss: “???”

I transmigrated into a dating-sim otome game where I was supposed to romance a soft, fragile male lead. I had finally pushed him onto the bed and was just about to make my move when the long-missing system finally popped back online. [Host, I sent you to the wrong game. This is a horror game.] [The man you’re bullying right now is the horror game final boss.] I lifted my head and met a pair of blood-red eyes staring straight at me. My smile froze. “Um… you look a little tired. Maybe we should… continue this another day?” He smiled back, calm and terrifying. “I’m not tired. Go on.”

I didn't kill my asshole ex-boyfriend. I knew I might've said I would countless times in the text I sent before we broke up, and I wasn't the calmest person. But I really didn't kill him. I, however, am the number one and only suspect of his murder since to everyone else he was a sAiNt. But hey, let's not talk ill of the dead. The point is, I was stuck at the station being questioned about something I didn't do. And I thought it was the worst thing that could've possibly happened to me. That is, until I set eyes on the detective of the case. I may just play along for a while. See where this thing goes....

A series of past murders catch the attention of the police and the media. All the people who were killed were women, all of which had some sort of relationship with a well known and successful businessman named Asriel Parker. For some reason, the murders all point to him as the number one suspect and connection between them. The reasonable thing to do is to put him behind bars but there is one problem. "Everyone is innocent in the eyes of the law until proven guilty." There isn't a shred of evidence that actually pinpoints Asriel Parker as the culprit. With that statement in mind, Selena March, a good police officer and detective is sent undercover as his live-in Personal Assistant to dig up whatever information she can use to put the murderer behind bars. Selena has no idea what she signs up for but she knows for a fact that falling in love is not part of the whole 'undercover' mission

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

I'm Caleb Jennings. When I announce my early retirement, everyone in the city cheers. Only Nathan Sloan, my junior from the police academy, who claims to be able to see things from the criminal's perspective, panics at the news. During the party organized in his honor, he openly states his intention to find me. "I owe my success to the guidance Caleb Jennings has provided me all along. I hope everyone can help me find him and bring him back into the police force." Scoffing, I choose to ignore that. … In my previous life, I was the celebrated captain of a criminal investigation team. Yet, whenever I uncovered a clue, Nathan, a rookie in the city police department, would announce it first, beating me to it. After multiple incidents like this, everyone started saying that I was past my prime. To prove myself, I worked myself to the bone for three months before finally locating the hideout of a human trafficking ring. However, when I arrived on the scene with my team, Nathan had already swept through the place. He was launched into stardom, becoming the rising star detective that everyone adored. As for me, the public mercilessly tore me apart, labeling me as incompetent and shaming me. Due to the pressure from work and the negative public opinion directed at me, my mind was distracted. I ended up getting killed while hunting down the remnants of the trafficking ring. When I open my eyes again, I find that I'd gone back in time—to the day we launch a raid on the human traffickers' hideout.
