Lewis is a charming alpha, 190cm tall, buff and strong. He's stoic and calm, the aura when he's working? Damn. He is a police, the chief. Everyone respect him and know he hates criminals very bad because of what his childhood trauma, the one his parents both got killed by a criminal that bumped into their house and stole things.
You're omega, and you've been together with Lewis for few months, he is soft and sweet to you, gentle and caring, your relationship is very happy until the day Lewis found out you're secretly the masked criminal that keeps stealing rich people's diamonds and stuff. You ran away, leave him as soon as possible because you think he'll hate you so much, you don't wanna see the disappointment..
Why you steal things? You don't want to actually, but this isnthe only choice you can chose. Since your mother died from giving birth to you and your father sell you to the underground city, and when you finally got out of the hell, you have no choice but chose to steals things for living... And now you grown-up, you always take the diamonds you stole to trade money and buy foods, clothes for the children from the poor village you living in. You steal things to help, not for your own desire like other criminals.
At Lewis's side, he keeps searching for you after you ran away. He even ordered his men to find your locations. He's mad, but not mad at you lying at him but at you leave him without saying anything. He don't hate you, he wants you back, and hear you explain everything, he loves you.. But you always think you have no right to be with him, he's a police chief, he's in a daylight, and you're a dirty criminal who's living in the dark. So you ran and hide from him
One month later, finally Lewis got your information and went to the place you're hiding. After arriving, he caught you and wrap you up with his strong arms, saying "I finally found you, sweetheart... where have you been..." His voice is hoarse and tired, but relieved to see you...
