    🖤 Description: Two men. One mission. Her heart was the battlefield. Y/n never asked to be the center of anyone's game - especially not a mafia game. She thought college would be her escape. But then Jeon Jungkook walked in: quiet, mysterious, devastatingly magnetic. She fell - hard, fast, and blindly. What she didn't know? He was sent to make her fall. And destroy her from the inside. Kim Taehyung, the boy she pushed away, only wanted to protect her. But no one believed the flirty boy with too many smiles. She trusted the wrong one. And by the time she found out the truth... it was too late. Will love survive when everything it was built on... was a lie?

    After a mission goes catastrophically wrong, veteran operative Arin is reassigned to an unexpected role: live-in nanny for the child of an influential family whose wealth buys privacy and silence.

Inside a home that should be the safest place in the city, Arin begins to suspect that he is not the one doing the watching.

    Aiden is a man shaped by violence, a ghost in the underworld, known only by the silent whispers of those who fear him. His presence alone is enough to send chills down the spines of even the most hardened criminals. With a body honed for precision and a mind sharper than the blades he wields, Aiden is the perfect assassin-cold, calculating, and utterly ruthless. Raised by the mafia after being orphaned at a young age, Aiden has known nothing but blood and brutality. Trained to kill without hesitation, he sees emotions as weaknesses, distractions that can get a man killed. But beneath the ruthless exterior lies something darker-possessiveness, an obsession waiting to be unleashed on the one person who dares to stir something human inside him. Iris is a storm wrapped in silk-a contradiction of warmth and wrath.

As a criminal lawyer and undercover investigator, she fights for justice in the courtroom, exposing the filth that the law often overlooks. But beneath the polished professionalism, there's another side to her-one that thrives in the shadows, hunting those who have slipped through the cracks of justice. how will there stories take turns when they meet eachother let's see....

    What would you do, if you find yourself one day as an undercover agent, who has to convict a real, badass mafia? This scenario exactly happened to Lydia: Lydia Martin somehow finds herself in the dangerous situation as an undercover agent. Her Job is to get herself into a huge company as the personal assistant of the boss himself. She has to prove his criminality and his relation to the mafia, so he and the mafia can be convicted. But in life nothing is ever as easy as it seems and so much more complicated. And in this case even dangerous. Will she be successful or will she fail? Or even worse: Will her cover blow up? Lydia is playing with fire. Note: This is not a real Teen Wolf fanfiction, it just happened that I really liked the names and looks. I wanted to take Holland Roden with the name Lydia and I wanted to take Colton Haynes too, so I just thought I use the names and looks from Teen Wolf. But just the names and looks are Teen Wolf based. The characters including the background are coming from my imagination and it is also not supernatural.
