Sirius

"It's the end of the world!" Sirius exclaimed.

I held in a groan as me and Remus looked at each other.

"Mr. Black, I don't think a paper cut requires you to go to the hospital wing." McGonagall said calmly.

"GOODBYE CRUEL WORLD!" He yelled.

"Mr. Black-"

"TELL JAMES' PARENTS I LOVE THEM!"

"Mr. Black!"

"(Y/N)! I LOVE YOU!" He yelled.

"Detention Mr. Black." She said sternly.

"Why are we friends with him again?" I asked calmly.

"Because he is like a lost puppy, you give them kindness and they follow you around." He said calmly.

"I thought you loved me (y/n)." Sirius said with a pout.

"Who are you?" I asked with a smirk.

He let out a whine and I rolled my eyes as he placed his head on my shoulder. Soon class was over and I walked beside Remus.

"(Y/n)! Love me!" Sirius exclaimed.

"Remus who is this strange guy following us?" I asked calmly.

"I don't know, let's keep walking." Remus said with a smile.

We made it to the common area and I smiled as I plopped down on the bed. Sirius put his head in my lap and let out a groan.

"Sirius stop being a baby or I'm going to stop talking to you." I said calmly.

"I'll behave.... if you kiss me." He said with a smile.

I rolled my eyes and leaned forward and kissed his cheek.

"On the lips. A kiss on the lips."

"You said a kiss, didn't say where." I said as I pulled a book out.

He let out a groan and laid his head on my lap again. I stood up and stretched, while he looked at me confused.

"Where are you going?" He asked softly.

"Room, I'm tired. Night Sirius." I said as I walked u other stairs.

"Night, (Y/n)." He said softly.

I walked up stairs and let out a sigh as I plopped down on my bed.

"You okay?" Lily asked softly.

"No.... Sirius is getting on my nerves. He keeps acting immature." I said with a groan.

"Well what do you expect? He is a child." She said calmly.

"Yea.... but if he wasn't childish... I wouldn't love him. ." I said softly.

I soon went to sleep and the next morning I noticed that Sirius was acting strange. He wasn't whining or joking about anything. When I set near him instead of cuddling up to me he scooted over and then in McGonagall's class when he got a paper cut he didn't whine about it.

"Is everything okay with Sirius?" I asked softly.

"I don't know. He has been acting strange since last night, he came to his room and instead of talking he just went to bed." Remus said softly.

"Did he say anything?"

"Something about being childish." James whispered.

I frowned as I stood up and grabbed Sirius' arm.

"I need to talk to my idiot." I said as I dragged him out of the classroom.

We stopped outside and before he could say anything I smacked him over the head.

"What was that for?" He asked shocked.

"You are so childish! Acting different when you hear me say something.... maybe if you would of continued to listen you would of heard that I loved that about you!"

"I thought you said that if I wasn't childish you would love me." He said softly.

"No I said that if you weren't childish that I wouldn't love you... I love you being childish. Yes sometimes it can be annoying but it's why I started to date you... it makes me laugh when you act all dramatic over a paper cut, and I love when you snuggled up to me at lunch... it makes me feel loved.... but you acting like this.... it isn't my Sirius... not the Sirius I fell in love with." I said softly.

"I'm sorry."

"Just be my Sirius.... please." I said softly.

He nodded his head and pulled me into a hug. He kissed my forehead and I smiled as I laid my head on his chest. We soon made it back into class and I smiled as I listened to him joke around with James.

"Good job." Remus whispered.

Soon we left class and I rolled my eyes as Sirius wrapped his arm around my waist.

"Give me kiss." He said with a smile.

"Will you shut up?"

"Never." He said as he leaned down and pecked my lips.

"Good." I whispered as I kissed him back.
