Negan was standing with his men and Lucille when, out of no where, a cute little girl runs and hugs his leg. Negan is super confused at looks at his men for support. They all shrug and Negan nods for them to move on before kneeling down to the girl.
"Hey, what's a cutie like you doing way out here?" He asked.
"Daddy!" She squealed.
"What?"
"Daddy!" She repeated.
"Sweetie, I'm not your dad. You must be lost," Negan looked at the small child.
"Daddy! Mama misses you a lot."
"What?" Negan asked. He was looking around like 'what kind of sick joke is this'.
All of a sudden you run out, grabbing your daughter.
"Oh my! I'm so sorry!" You apologize.
"Er - did I have an affair that I don't know about?" Negan asked, causing you to laugh at the ground at his charm.
"No. I promise you. You just look like my husband and she probably got confused. We lost him at the beginning," you explained.
"Oh, well, in that case. I'm Negan, and I'm currently single," he smiled at you. Your daughter ran up to him and hugged his leg again.
"Daddy!"
"Y/D/N, this isn't Daddy. This is Negan," you kneeled down to your daughter. "I'm sorry sir. She's still young and she can get really confused."
"It's fine.... um...." Negan started to try and guess your name.
"Oh, how rude. I'm Y/N and this is Y/D/N," you introduced. Negan nodded and decided to take you with him. At first he scared you, with his baseball bat. But then he started to become more of a father to Y/D/N. She loved him and usually called him "Daddy N" or "Daddy". Negan didn't seem to care that she was not his, she still loved him and he wouldn't let a thing happen to her.
One time, he took her outside with his men, and one of the men started to act stupid. Negan tried to scold them but it was hard to do with a pretty little girl in his arms. I mean, come on, what's cuter than a tough guy holding a three-year-old girl?
Another time, you walked in when he had fallen asleep and she was on his chest, also fast asleep. His hair was a mess, and Y/D/N had one hand in his. Her little hand in his large one was an adorable picture that could be used for blackmail anyday. You shut the door just in case another worker walked by and walked over to Negan, gently grabbing Y/D/N and starting out. Negan groaned before sitting up and looking around, not seeing your daughter. You hid behind a dresser to see his reaction and he immediately grabbed Lucille in case she was kidnapped. You felt bad for the man and walked into the open, showing Negan your daughter.
"Oh shit.... you scared me!" He said, trying to catch his breath. You simply laughed and put Y/D/N down on his bed.
"Sorry."
"You best be!" Negan said, wiggling his fingers to your sides. You giggled and poked his stomach, causing him to jump and laugh. You ignored it, for now, and he pulled you into a kiss. You were startled at first but then you gave in and wrapped your arms around his neck. When he pulled back you saw that he was blushing for the first time.
"Never seen you blush," you smiled at him, causing him to go redder. You kissed his nose. "It's cute."
"Well, you ain't blushing, so I don't know why I am," Negan walked back over to his bed and you followed him. Once he was nice and comfortable with Y/D/N on his chest, you kissed his cheek softly and moved to your room, which was right beside his.
This was the start of a great relationship.

I don't like Negan but a lot of people do. I would like him if he hadn't killed Glenn and Abraham. He was cute before, now everyone's flicking him off. This was fun to write tho.
Peace and Love.
