For misstrishx
I hope this is okay😅

I was out for dinner with my boyfriend and his brothers tonight. I felt a little embarrassed as the only reason we were out and about was because it was my birthday. I told Choromatsu many times that we didn't need to do anything for my birthday but of course he didn't listen. So here I was eating with my head down. It wouldn't have been as embarrassing if it was just Choromatsu but I had no idea why his brothers were here.

Don't get me wrong, I like his brothers and I get along with them. I just didn't know why they came along. Surely they had better things to do.

"You have been quiet."

I flinch and look up at Choromatsu. "You okay y/n?" He asks and I blush "I..Well..I'm just thinking." I say and he hums "Well...I mean no offense but...why did your brothers join?" I ask and shy away as they all turn to look at me. "I m-mean aren't t-they b-busy people? Surely they're just wasting time being here."

It was silent before I hear a soft laugh from Karamatsu. "You shouldn't think like that. It is our choice to be here dear." He says and the others nod. "Yeah, don't go putting yourself down." Ichimatsu says with a smirk as he adjusts his glasses "We would never want to your birthday!" Jyushimatsu says with a soft smile and I blush. "I still feel like you guys could have stayed home or something." I say with a pout and I hear a chuckle from Osomatsu.

"Aw~ did someone want to be alone with Choromatsu?"

I lift my head with a blush and that makes the brothers, except Choromatsu, laugh. I glance at Choromatsu to see him with a soft smile. I blush as he wraps his arm around my waist. I try to scoot away but he pulls me to his side. He chuckles and kisses my temple "Hm? Why you scooting away?" He asks and I blush as I squirm "P-Please just let me go." I say with a blush as his hand rubs my admittedly chubby side.

He hums and I squeak as he squeezes my side. He chuckles and kisses my cheek before leaning up to my ear. "Do you not like when I do that?" He asks in a whisper and I kept silent with a blush. He pulls away with a smile and pets my head. "Cutie." He mumbles and I blush before looking down as I went back to eating.

Even if at first I was hesitant about having all the brothers at my birthday I ended up having a good time. When everything winded down Choromatsu walked me home. When I walk into my house I turn to Choromatsu before I hug him. "Thank you. I had a lot of fun." I say and he hums as he hugs me back. "You're welcome. Happy Birthday." He says and went to pull back but I hug him tighter with a growing blush.

He hums and I look up at him. "Um..about what Osomatsu asked...I actually d-do want to spend some time with you...a-alone." I stammer with a blush and he looks at me surprised before he smiles. "Oh okay~" He purrs and kisses me. I blush and kiss back before pulling away. I took his hand and pull him into my house where I got the alone time I wanted.

Choromatsu has always made my birthdays better but this was officially the best birthday I have ever had.
