There is something strangely compelling about being told to stay away from someone, only to find yourself wondering what might happen if you stepped a little closer. That is the dangerous little spark at the heart of Criminal Hearts: Obsession Bad Boys Dating Sim, a dark romance visual novel from Red Fables that swaps school corridors and awkward teenage crushes for neon streets, secret meetings and men with very good reasons for keeping their distance. This is a dating sim where the butterflies come with a side order of danger, and getting emotionally attached might be the least sensible decision you make.
The premise wastes little time establishing the mood. It is 3am You are on rooftops. Deals are falling apart in back rooms, and there are three men standing between you and what could be either an unforgettable romance or a spectacularly bad idea. One barely speaks. Another seems incapable of stopping. The third is perfectly happy to tell you exactly what sort of man he is. The interesting part is that none of them expected you to become involved, which immediately gives the story a slightly more unpredictable edge.
Welcome To The Wrong Side Of Town
Criminal Hearts understands that a dark romance needs atmosphere. There is a world of difference between falling for somebody in a cosy café and falling for somebody while wondering whether the conversation you are having could get you killed. The game’s criminal underworld setting gives even relatively simple exchanges a sense of tension, as there is always the possibility that something more serious is hiding behind the words.
The presentation plays its part beautifully. Anime-inspired character artwork gives each of the three central men a strong visual identity, while the city backgrounds create a suitably moody backdrop of neon lights, shadowy streets and secluded safehouses. It is not trying to reinvent the visual novel format, but it does not need to. Sometimes a well-chosen background, a good character portrait and the right piece of music are enough to make a conversation feel considerably more important than it might look on paper.
The synth-driven soundtrack is particularly useful in setting the tone. Tense moments are given a suitably uneasy pulse, while the music becomes softer when the story moves towards more intimate encounters. That contrast works because Criminal Hearts is constantly balancing two very different ideas: the excitement of romance and the very real possibility that getting too close to somebody could end badly.
Three Men, Three Very Different Problems
The three romantic routes are naturally the main attraction, and the game wisely avoids making them feel like variations of the same character. Each man has his own personality, secrets and reasons for keeping people at arm’s length. One is quiet and difficult to read, another is more openly expressive, while the third almost seems to challenge you to discover just how dangerous he really is.
That creates an enjoyable sense of curiosity. You are not simply choosing which handsome character you prefer from a menu and then following a predetermined romantic path. There is an element of discovery because getting closer to somebody means understanding how they react to what you say and, just as importantly, what you choose not to say.
The writing is strongest when it allows those personalities to clash with the protagonist. There are moments when honesty feels like the obvious answer, yet the dangerous answer is often the more interesting one. Push somebody too far and the consequences can be immediate. Handle a conversation carefully and you might be rewarded with a confession or a glimpse behind the carefully constructed persona.
That makes the relationships feel more fragile than in a conventional dating sim. Trust is not something you simply fill up with enough correct answers. It feels more like something you are constantly negotiating.
Every Word Has A Price
Choice-driven storytelling lives or dies by whether decisions feel meaningful, and Criminal Hearts makes a solid effort to give its dialogue choices weight. You are regularly faced with decisions involving honesty, defiance, silence and emotional vulnerability. There is rarely a flashing sign telling you which response will produce the best result, so you have to judge the situation and the person standing opposite you.
That uncertainty is one of the game’s most enjoyable qualities. Sometimes you might choose an answer because it feels right for the protagonist, only to discover that the person you are speaking to interprets it completely differently. Other times, saying less can be more powerful than trying to force a confession. The possibility of shutting down a relationship through a single poor decision gives conversations a little more bite.
There is also something refreshing about the fact that failure is part of the experience. Not every route has to end with romance, and not every relationship deserves a happy ending. Redemption, ruin and obsession all sit on the table, giving the story room to explore the darker side of attraction rather than treating romance as an automatic reward.
The Companion Who Knows Better
One of the more welcome touches is the presence of the player’s companion. In a genre where protagonists can sometimes spend an alarming amount of time making obviously questionable decisions without anyone commenting on them, having somebody in your corner who actually reads the room is a welcome change.
The companion can offer perspective, tell you when you are being foolish, and, importantly, does not simply agree with everything you do. That gives the protagonist’s choices a useful counterbalance. You can still make the reckless decision, of course, but somebody is there to remind you that perhaps walking into a criminal safehouse alone at three in the morning was not the finest plan in the world.
It also helps the protagonist feel less isolated. Even when the central relationships become intense, another voice reminds you that there is a world outside the romance routes. That small addition gives the narrative a little more personality than a straightforward sequence of conversations between the protagonist and her chosen suitor.
Romance With A Criminal Undercurrent
The mystery elements help prevent Criminal Hearts from becoming nothing more than a succession of romantic conversations. Investigating contacts, examining evidence, and trying to understand hidden motives give the story another reason to keep moving forward. The criminal setting therefore becomes more than window dressing, as the relationships are tied to the mysteries surrounding the characters.
This is where the game’s darker tone works particularly well. Discovering something important about a character does not necessarily make them safer or more appealing. Sometimes it does precisely the opposite. The more you learn, the more complicated your feelings can become, which is exactly what a story about dangerous attraction should do.
There is a nice tension in the way romance and investigation overlap. Learning somebody’s secret can bring you closer to them, but it can also give you information that makes you question whether you should trust them at all. That uncertainty gives the narrative its strongest moments.
The Joy Of Playing It Again
Multiple endings are essential in a game like this, and Criminal Hearts gives you a good reason to revisit its routes. Different decisions can send relationships in different directions, so your first playthrough is unlikely to reveal everything the game has hidden away.
The unlockable CG artwork also gives repeat playthroughs a little extra purpose. Romantic visual novels have always been good at making players want to see every important scene, and a gallery provides a satisfying record of the moments you have discovered. More importantly, knowing that different choices can reveal different outcomes encourages experimentation.
There is particular satisfaction in replaying a conversation where you previously made a mistake and choosing differently. Sometimes the smallest change can lead somewhere completely unexpected. That is the kind of replayability that works naturally for the genre rather than feeling artificially bolted on.
Not Quite The Revolution, But A Good Dark Romance
It would be unfair to suggest that Criminal Hearts completely reinvents the dating sim. Its core mechanics are familiar, and anyone who has spent time with choice-driven visual novels will immediately understand how the system works. You read, choose, build relationships, and see where those decisions take you.
But familiarity is not necessarily a weakness. The important question is whether the ingredients come together effectively, and here they largely do. The darker setting gives the familiar formula some personality, while the three central characters provide enough variety to make exploring the different routes worthwhile.
What I particularly like is that the game does not pretend that dangerous men are automatically romantic simply because they are dangerous. There is a difference between fascination and trust, and Criminal Hearts has fun exploring that uncomfortable space. Sometimes attraction draws you towards somebody long before common sense has finished screaming that you should probably walk away.
The Verdict
Criminal Hearts: Obsession Bad Boys Dating Sim is a game built around the seductive pull of bad decisions. Its criminal underworld setting gives the familiar visual novel formula a darker edge, while the three romantic routes offer distinct personalities and secrets to uncover. The writing shines when it makes you question your own choices, particularly when an apparently harmless line of dialogue can shift the direction of a relationship.
It is not going to radically change the visual novel genre, and its mechanics will be comfortably familiar to anyone who already enjoys dating sims. What it does have is atmosphere, personality and a genuine understanding of why dangerous romance can be so entertaining. There is something satisfying about being given every opportunity to make the sensible choice, only to deliberately choose the option that could make everything considerably more complicated.
The strongest compliment I can pay Criminal Hearts is that it makes you curious. Curious about what these men are hiding, curious about what happens if you push a conversation further, and, occasionally, curious about just how badly things can go. That is enough to keep the pages turning, and in a genre built almost entirely around the desire to discover what happens next, that matters.
