Eternally His (Dazai Osamu x Reader)

Happy Birthday!

Your P.O.V.
I gently pushed on Dazai to wake him up, he groaned softly before turning over and looking at me while rubbing his left eye, "what's wrong baby?"

He blinked a few times then concerned Dazai was activated, he quickly sat up and stared at me, examining my body, "is something wrong? Do you need something? Are you in pain? Discomfort maybe?"

"No Osamu." I told him and pointed at the clock, it read 11:42am.

"Okay? What about it?"

"It's June 19, idiot."

"Oh! My birthday!"

"Yea." I rolled my eyes before taking a deep breath, "thank you for everything Osamu."

"You know I always did have a thing for you calling me by my first name~" he teased

"Shut up." I pushed on him, "I love you dummy."

"I love you too." He hugged me gently, making sure not to squeeze me.

"Uhm- for all the years we've spent together have been some of the best of my life. You make me forget who I once wa-" I was cut off by Dazai's lips.

He pulled away and looked at me, his chocolate eyes filled with affection, "y/n darling~ save that for your vows."

"No one said we're getting married!"

"I did!" He said playfully, he began to tickle me. I laughed before trying to push him off. He planted another small kiss on my forehead before saying, "okay fine since no one said were getting married, should I propose?"

"Dazai, we're too young. I don't want to get married at 18."

"19?"

"Maybe 25."

"Noooo~!"

"I didn't even want to have a child this early but of course Osamu Dazai has to make all of the decisions by himself."

"I- yea that was on purpose."

"You bitch!" I smacked his shoulder before turning my head, he hugged me, "so at 19?"

"25." I said sternly.

"20."

"23."

"22?" He asked now intertwining our fingers.

I sighed before tightening my grip on his hand, "22."

"Yay!" A big smile was plastered on his face.

We sat in bed most of the day, after a while I began to talk to him while he laid his head on my lap, I was playing with his hair, "you know...I'm scared."

He turned his attention to me, "hmm? Why baby?"

"B-Because, we're going to have a child and I don't know if I'll be a good mother..." I said softly

"Y/n." Dazai lifted up, he looked me in the eyes with a serious expression, "you have to understand that there is no such thing as perfect parents. We're going to make mistakes, we're not going to be 100% amazingly perfect parents, we're still kids ourselves-"

"I wonder who's fault that is."

"Hey! Let me finish!" He pouted before turning serious again, "as I was saying, as long as we learn from the mistakes we make, we'll be fine. I know both of us will struggle at first because neither of us have come from an actual household nor have we both lived normal lives but we will be good parents."

I nodded and wrapped my arms around his neck, then I heard the door. I smiled then got up, "I got it."

"F/n L/n, you get back in this bed right now!" He said playfully yet sternly

"No!" I stuck my tongue out then proceeded to walk towards the door

"Y/n~! Wait for me!"

I opened it to see Atsushi, I brought him inside before Dazai got out of bed, he set a box on the counter, "thank you."

"You're welcome L/n-san."

"Please just call me Y/n."

"Are you sure that's okay?"

"Atsushi?" Dazai's voice echoed from behind me, "what are you doing here?"

"T-The cafe downstairs wanted to me deliver your tab!" He immediately said, Dazai scratched his head then turned to leave.

"Osamu." I said slowly, "I thought I told you to pay your tab a month ago."

"Whaaat?! No way!"

Atsushi looked at the two of us, completely unsure what to do.

We began arguing while Dazai threw jokes around here and there. Atsushi walked to the door, "I'll be uh- leaving then...!"

We heard the door close then we stopped speaking and it was soon replaced by laughter, "what's that?" Dazai asked pointing at a white box that Atsushi had brought over,

"Hmm?" I turned my attention to the box, "Oh!" I walked over to the counter and grabbed a knife, I opened the box and showed him what's inside.

"Aww~ a cake!" He said before wrapping his arms around my rounded tummy.

"You want a piece now or later?"

His hands rested on my hips and he put his head on mine, "if you're feeling alright, can we go out?"

"That wasn't the question but sure."

I told Dazai to put the cake in the fridge while I go get dressed and I have never had such a hard time dressing myself, I felt something move. I immediately called for Dazai, "Dazai! Come here!"

He ran into the room panicked, "no nothing's wrong you big oaf!" I grabbed his hand and placed it on my stomach, I watched his expression as he felt the baby kick.

His lip quivered, while his eyes softened he looked at me with tears in them, "I-I'm so happy." He said before smiling

"Nevermind! I don't want to go out anymore. Let's just get the cake, and spend all day in the house watching Netflix! So I can feel the baby kick all day!" He said excitedly.

I looked disappointed because I just struggled to get dressed, "if you want I can undress you~"

"Get out asshole." I said before throwing my shirt at him. He chuckled before walking out and getting everything prepared, he peeked in to see if I needed help. I sat down frustrated because I was having a hard time taking my pants off.

I felt something pull on me and I looked down to see Dazai, sliding the pants off with ease, "you don't have to flex." I said turning my head

"Well, I couldn't just peek and watch you fail." He laughed in his hand

"You perv!" I said before lightly kicking him in the side. He chuckled again before picking me up and putting me into the bed, we cuddled and watched Netflix.

"Hey Chibi."

"The fuck you just call me?!"

"Chibi~"

"Fine, I'll allow it but once I have this child you're getting your ass whooped."

"Thank you for today." He said kissing the top of my head. My face heated up before nodding, "thank you for being born." I kissed his cheek before we turned our attention back to the tv.
