LifeLine// BTS mafia AU (Completed)

11: Really?

They both stop and turn to look at me "Do not say a fucking word Kim Soo Young" Yoongi warns lowly.

"Arianna we need to talk" my mother ignores Yoongi.

I look to Yoongi and he shakes his head but I look to Namjoon and he gives me a slight nod; for which he earns a glare from Yoongi for.

"I'm not sitting so just explain" I say sternly.

My mother sighs and Yoongi continues to glare at her but he also looks scared and disappointed "Not long after your father and I got married I found out he was having an affair."

I shrug "Honestly doesn't surprise me, but continue."

"The woman he was having an affair with got pregnant and your father tried to convince her to get rid of it but she refused."

I nod "Okay, what does this have to do with you two yelling at each other."

"The woman he was having an affair with and impregnated was Yoongi's mother."

I furrow my eyebrows in confusion at first but then it hits me "So Yoongi is my brother."

My mother nods her head "Well half-brother; but yes."

I turn to look at Yoongi, a powerful look in my eyes "And you knew the entire seven years I've been here and never thought to tell me?"

"I've known since I met you, I knew before I met you. But your father didn't want you to know about me."

"After I killed him why didn't you tell me?"

"I know how much you hate it when people keep things like that from you especially about the truths of your past and family. I didn't want you to be angry with me."

"Yoongi if you had just said something then I wouldn't have been angry, but having to find out from my mother after having to break you two out of a fucking argument over it." I take a breath "I'm not angry." Yoongi sighs in relief but I shake my head "But I am disappointed."

He let's his head hang and he stares at the floor "I'm sorry Ari."

I sigh "Just give me some time to process this okay?"

He nods and I pull him into a hug before going back upstairs to Jungkook and climbing in bed with a sigh. "What's the matter babe?"

I shake my head "I don't want to talk about it right now."

Jungkook nods and kisses the top of my head "Okay."

I sigh again and play with the hem of Jungkook's shirt "We need a vacation Kook."

"Agreed."

Jungkook plays on his phone while I watch an American TV show. I'm cuddled into his side and he keeps my head tucked under his chin; rubbing softly and consistently, up and down my side, trying to comfort me. It works but I continue to get lost in thought.

Hoseok comes home a couple hours later, placing a kiss on my temple and pecking Jungkook's lips. He showers and changes before climbing in bed, laying his head on Jungkook's hip. Jungkook moves his arm so it's on Hoseok's chest and he can still look at his phone.

"Hoseok?"

"Yeah babygirl?"

"Did you know?"

He looks at me confused; eyebrows furrowed "Know what my love?"

"That Yoongi is my half brother."

He shakes his head "No I didn't know. Knowing your father it was more than likely a secret between him, your mother, Yoongi, his mother and his step father. I mean I knew Yoongi's dad wasn't his biological father but I had no idea who his biological father was."
