Niall: Being Niall Horan's bonus child was not what you thought it would be. You were expecting him to treat you like a princess and be like a dad to you. You had lost your dad in an accident when you were two years old, you didn't remember any details. It was though growing up without a dad, but you did it, your mum was always there for you. You never had any problems with accepting Niall. It was the other way around, he couldn't accept you.
"Y/N, I have to work extra today, so you'll have to stay with Niall" your mum told you. You just nodded, you didn't want to argue with her.
20 minutes later your mum was off for work and you were stuck with Niall. He was watching TV in the living room when you walked in and sat next to him.
"What's up?" You asked sweetly trying to make a conversation.
"What do you want Y/N?" He asked rather harshly.
"Um ... I was just ..." He cut you off.
"You were just about to go upstairs, right?" He said.
"No, I was actually about to make a convo with you!" You snapped. You couldn't believe that you just snapped at Niall.
"Y/N if I ever wanted to make a convo with you I would! But I have never tried since I don't care! I only accept you since you're Y/M/N's daughter" It felt like he ripped your heart out.
"In fact you haven't accepted me for two shits! You ignore me, you can't stand me and the worst thing is that I don't have a clue of what I've ever done to you" you yelled and ran upstairs with tears running down your cheeks.

Niall's POV

When I saw the small little human run up those stairs my heart broke. I was asking myself what was wrong with me, Y/N never deserved this. I was rude towards her for no reason what so ever. I guess it had to do with my exceptions, I always thought that I would find a woman, marry her and have kids, but I found a woman who already had a kid herself. I heard faint sobbing coming from
Y/N's room. Before I could even think twice I was on my way to Y/N.
I didn't knock on the door, I just opened it and entered. The sight broke my heart, she was lying on her bed crying her little heart out, I sat on her bed and pulled her into a hug.
"I'm so sorry baby girl! You never deserved me to treat you the way I did! And I promise you that it'll never happen again! "
" Why did you treat me like shit?" She asked, I mentally noted to scold her later for cussing.
" I always had the idea of marrying a woman and then get children, but your mum already had a child herself, even tho it's an bad excuse ... I'm sorry! "
"Oh ... I understand" she whispered and wrapped her arms around me.
" I promise you that I'll treat you better! By the way stop cussing!" I joked.
"Yes sir!" I laughed and kissed her cheek, we ended up spending the whole day together.
