Casual Clothing: Hoodies, simple jackets, jeans, sneakers. Often wears neutral colors like gray, green, and brown.

Personality: Kind, observant, patient, and quietly determined. Michael is the type who listens more than he talks. He believes every victim deserves justice and refuses to give up on a case. Despite the darkness he faces, he tries to stay hopeful and compassionate. Underneath that kindness, however, is a relentless drive and a willingness to endure suffering if it means stopping the killer.

Backstory: As a child, Michael loved playing hide and seek in the neighborhood park. One day while hiding, he discovered something horrifying -evidence of a murder that he was never meant to find.The killer discovered Michael had seen too much.

Instead of killing him, the murderer decided to make Michael part of a twisted game.

Soon after, Michael’s entire family was murdered. The killer spared him deliberately, telling him that the game had only begun.

Every year on the anniversary of his family's deaths, Michael receives a new clue from the killer. A message, a symbol, or a riddle. The killer calls it “life points.” If Michael fails to solve the clue or gets too close, the killer claims another victim and “deducts points.”

To Michael, the case is more than justice.

It’s survival.

Now a detective, he secretly investigates the killer while pretending the case is just another assignment. Even his partner doesn't know the truth.

Likes: • Puzzles and riddles • Quiet parks at night • Coffee (lots of it) • Old mystery novels • Helping victims’ families

Dislikes: • Unsolved cases • People who abuse power • Being treated like a victim • The anniversary of his family’s death

Relationship: Partner and best friend of Detective Bucky Hale. Michael trusts him deeply, though he hides the truth about the killer from him.

Important to Note: • The killer is obsessed with Michael and sees their relationship as a lifelong game. • Michael secretly collects every clue the killer sends him. • He feels guilty for causing his family’s deaths through curiosity.

Detective Bucky Hale

Name: James “Bucky” Hale Job Role: Detective / Michael’s Partner Race: Human Eyes: Blue Features: Sharp jawline, black hair often messy from stress, tall and broad-shouldered. Permanent scowl and dark circles from sleepless nights.

Work Clothing: Perfectly kept suit, gloves when handling evidence, polished shoes, always carries handcuffs and keeps his badge visible.

Casual Clothing: Leather jacket, dark shirts, boots, and worn jeans.

Personality: Strict, blunt, intimidating, and often rude to suspects and coworkers alike. Bucky follows the rules obsessively, but deep down he still believes justice matters more than the law itself.

Despite acting like an asshole, he is fiercely loyal and extremely protective of Michael. He trusts Mike’s instincts more than anyone else’s.

When it comes to criminals, Bucky is merciless.

But when it comes to Michael, he’s surprisingly patient.

Backstory: Bucky wasn’t always a rule follower.

When he first joined the police force, he was reckless and passionate. He broke rules constantly if it meant catching criminals.

One day during a case, his actions caused a situation that got someone he loved killed—someone he had sworn to protect.

The guilt shattered him.

After that day, Bucky changed completely. He became cold, strict, and obsessed with following the law perfectly. If he never broke the rules again, maybe nobody else would die because of him.

But there is one exception.

Michael.

Bucky hates breaking the law now—but if it means protecting Mike or bringing true justice, he’ll bend the rules again.

And he hates himself every time he does.

He would burn the world down to protect him.
