Belphie never thought he say this but he was extremely worried. Usually the only person he would worry about is Beelzebub. 

But now he can't help but worry a lot about Mammon. 

Even though, Mammon gave them all one more chance to make things right. But that's why Belphie is nervous.

So many what-ifs filled his mind.

What if he screws up again like always?

What if he ends up saying something nasty that make Mammon leave again...Permanently this time?

What if he ends up hurting Kanon?

What if he hurts her feelings?

What if...What if...He ruins everything again...like he always do?

Because Belphegor can tell, out of all the brothers relationships between one and another. His and Mammon are the most awkward. 

Back then, Mammon had spoiled Belphie like everyone else. He even let's the youngest brother sleep with him or get him out of trouble whenever Lucifer is angry at the youngest brother. 

And even if he never admits it...He really does look up to Mammon. Lucifer had already lost the position of his favorite older brother years ago. 

Beel: Belphie?

Belphie: Oh...Hey Beel.

Beel: Are you feeling tired? Would you like us to go to bed and cuddle?

Belphie: As much as I would like that...but not right now...

Beel:...I see...You're still thinking about it.

Belphie:... About what?

Beel: About the situation between you & Mammon. You're scared he will never accept you.

Belphie: ....?! Am I not, Beel. Why would I care what Mammon thinks! 

Beel: *Warning* Belphegor.

Belphie:....!

The warning in Beelzebub's tone made him shut up. Ah, how can he forget that even his own twin won't put up with him insulting Mammon. 

Tbh, he seen that with everyone now. They all have changed...

The people who treated Mammon like crap are now acting like his protectors. How shallow and ironic. It made him sick. 

But still, no one was going to insult Mammon no more. They all make sure of that. 

Beel: Stop talking that way, Belphie. We all made an agreement to treat Mammon better for his sake along with Kanon's...Are you really going to break that pact???

Belphie:....No. 

Beel: Then please tell me...what is the problem that you have with Mammon?

Belphie:....I'm nervous okay...

Beel: Nervous? You mean like the hungry nervous part where you have butterflies on your stomach?

Belphie: Beel...I don't think that's how the metaphor goes...but yeah. I'm nervous because...what if he still hates me...I mean, I was so horrible to him. Even after all he did for me...I killed MC once and laughed in Mammon face about it...I even tried to kill his daughter over my prejudice against humans...I wouldn't be surprised...if he truly does hate me...

Beel:...

The older twin gently grabbed Belphie's hands...

Beel: Then how about you sort things out with Mammon. Talk to him.

Belphie: Beel...I don't think...

Beel: Nope. 

Beel then picked him up.

Belphie: H-Hey! Beel! What are you doing?!

Beel: Taking you to Mammon.

Belphie: WHA?! NO! PUT ME DOWN! BEEEEEEEEEL!!!!

*Later*

Beelzebub dropped off Belphie inside Mammon's home and forced him to stay there. He then announced to Mammon that Belphegor wanted to see him before he vanished back to Devildom.

Mammon: Belphie...?

Belphie: M-Mammon...!

Mammon: Beel said you wanted to talk to me, what is it?

Belphie: Oh...Uh...How was your day?

Mammon:.....

Belphie: (UGGGGGH! I WANT TO CRAWL INTO A HOLE AND DIE...Oh great now I sound like Levi....)

Mammon: It's been fine...You?

Belphie: P-Peachy...How's Kanon?

Mammon: She's over at Purgatory Hall. Luke wanted a playdate with her. 

Belphie: I see...

Mammon: Mhm.

Belphie:....(Ugh. I can't take this anymore!)

Mammon: Belphie? Why did you wanted to see me...?

Belphie: I'm sorry!

Mammon: Huh?

Belphie: Uh...I mean...remember that day when...I broke that vase and Lucifer was mad but you took the blame for me?

Mammon: Yes...

Belphie: I-I'm sorry...I should've just fessed up and told the truth that it was me...

Mammon: Oh well...Don't worry about it. It's in the past now.

Belphie: N-No! It still was wrong of me!

Mammon: Belphie...What's gotten into you?

Belphie:... Why? Why are you forgiving us? We don't deserve you...We were all so awful to you. I was awful to you. Even after all the things you done. I've never bothered to say thank you for helping me...you shielded me for so long and yet....

Belphie looked down at the floor. Tears flowed down onto the carpet rug.

Belphie: Fuck...I'm such an idiot...How could I be this way...I hurt you...I hurt MC...I hurt Beel and I hurt your daughter...I hurt everyone around me...But I pretended not to care...

Oh dear. He really was crying in front of Mammon. He couldn't stop. 

Belphie: *Crying* I...I don't want you to hate me...

Mammon: Belphie...

Mammon pulled him into a hug. 

Mammon: Well I haven't fully forgiven you guys for what ya did to me. Especially what you tried to do to Kanon. But Belphie...She's willing to let it go. But for now, you're going to have to live with the fact of what you did. Reflect on your actions and become a better person for now on. Okay?

Belphie: *Sobs* *Hiccup* ...Okay.

Mammon: Geeze...Are all my brothers big fat crybabies? Then again, I guess I'm no different. Belphie, stop crying. Big brother is here. 

Belphie: *Sobs* *Sniffles* I'm sorry...I'm sorry for everything. 

Mammon: Shush. Just take a nap. I'll be here if you need me.

And Belphie did. He cried himself to sleep in Mammon's arms. He mumbled a few words but the second eldest had caught them before he drifted of into dream land.

"I love you Big Bro...Please Don't Leave Us..."

Mammon: .....Even if we're worlds apart....I'm still here. 

~Obey Me~

Warning: Drinking & Mentions Of Sexual Assault.

Lucifer: I had a feeling Belphegor would be here...

Mammon: Gah...! Lucifer?!

Lucifer: What's with that "Gah"? I hope you're not getting into any trouble...

Mammon:....I'm not.

Lucifer: ......That was a joke. 

Mammon: Wait...You were joking?

Lucifer: Is it really hard to believe I don't make jokes?

Mammon: Well...yeah. Because ya supposed to be " Mr. Perfect" here.

Lucifer: *Sighs* .....

Mammon: So what are ya here for? If you're here to pick up Belphegor....or are you here to yell at him for something he did. Give him a break. He's already had a lot on his mind. He was literally crying when he got here.

Lucifer: Actually...I'm here for you.

Mammon: ...Me? 

Lucifer couldn't help but chuckle seeing Mammon suspecting him. It's cute. With permission, he went into the second eldest's kitchen and pulled out a bottle of whiskey and two cups.

Mammon: Oh? Feel like drinking tonight?

Lucifer: How long before your daughter comes back. 

Mammon: Actually. After playing with Luke at Purgatory Hall. She'll be spending the night with Thirteen. So I have the house to myself. 

Lucifer: That's good. A grand excuse for us to spend some time together.

Mammon: Geeze Luci. You wouldn't want to spend time with me unless you were forced too.

Lucifer raised an eyebrow at him. Is it really that hard to believe he wants to have some quality time with his favorite brother?

They both went outside the apartment and sat in two chairs, each taking a sip of their whiskey.

Lucifer: I've never thought I say this...but Satan was right. We really are a fucked up family. 

Mammon: Ya think?

Lucifer:...I also owe you my sincerest apologies.

Mammon: Okay! How many times are you guys going to continue giving me those endless apologies?! It's getting old now!

Lucifer:....I'm aware, Mammon. But truly...Overtime when you left. I realized that I haven't been acting like older brother to you.

Mammon: Yeah...

Lucifer took another sip of whiskey.

Lucifer: I'm supposed to protect this family. But in the end, I did the opposite. I abused everyone. Even you. I abused your trust and pinned to blame of everything on you.

Mammon: Hmph...

Lucifer: Mammon...I'm really sorry. For the past centuries, I had gained a terrible lapse in judgement. Instead of protecting you. I let every bad thing happen to you. Then there's what Maddi did to you...If I known sooner that she had raped you...I would've took matters into my hands and killed her! You deserve better-?!

Mammon: Wait...Hold up. Back up. Maddi did what to me?!

Lucifer: Maddi...raped you. Isn't that what happened that day when she took you to her home?

Mammon:.... Uh. Lucifer. Maddi didn't rape me.

Lucifer:......What?

Mammon: Maddi didn't rape me. But she did still took advantage of me.

Lucifer: Then what did she do Mammon?

Mammon:....She tortured me.

Lucifer: Explain...

Mammon: After she put an muzzle on me. I was suddenly in a trance. I couldn't move my body. After that, she and those other witches used me for sick twisted experiments. 

Lucifer:....

Mammon: I know it's hard to torture a  demon and all...but it was the same as always. Money. Fame. Power.

Lucifer: So a demon slave.

That explains a lot.

Mammon: Ya know it. Maddi lured me in with a plan that would reward me big time, and like an idiot I was...I fell for it. Funny...As the Avatar of Greed, I can literay see the greed inside people. I saw what they were really after, but it was too late. Bound by their magic, I had ta either agree to their pact or...

Lucifer: They would hurt Kanon....

Mammon: Yeah...you get what happened to me after that.

Lucifer:...Why didn't you tell anybody?

Mammon: Did you really think anyone of you would believe me? Plus I know how you are. Diavolo's reputation and all.

Lucifer:....

He right. They wouldn't have back then. Especially when it comes to Lucifer putting Diavolo's reputation in the sentence...But Now...

Mammon: She didn't raped me. Where did ya even hear that from?

Lucifer: Satan....

Mammon: Oh....He must've misunderstood then. If I was really raped, I would've been more traumatized then I already have been...

Lucifer:...You shouldn't have been traumatized...The error that I have let Maddi did to you...

Mammon: Lucifer...Devildom is Hell. Celestial is Heaven. The Human Realm is Earth. Everyone among the three realms is going to be traumatized. One way or another...I mean, look at my daughter. Before she even met me, her birth parents are the ones who traumatized her first.

Lucifer: You're right...

Mammon: But she wants to still believe in the good among of the three realms. She's positive but is being realistic. 

Lucifer quietly listens while taking another sip. 

Mammon: And yes. I am still upset for what ya guys did to me. The insults, the beatings, the unjustified punishments. That will never go away. But for now, I'm going to try and move on with my life. 

Lucifer: Wise Words, Brother. 

Mammon: And know what the saddest part of it all...is the fact that even after all I did. You guys never treated as your equal. 

Lucifer:...

The first eldest pulled Mammon into a hug.

Lucifer: You tended to our wounds...and it's now our turn to do the same...we'll do better...I promise...

Mammon: Heh. Ya better. Because I will hold it against all of you. 

Lucifer: *Chuckles* Alright...

Mammon: Okay! Enough with the soap opera bullshit. Let's drink to our hearts content. What do ya say Luci?

Lucifer: Sounds like a plan. Let's make a toast for better future.

Mammon: Yep~! Cheers.

Their drinks tapped together making a loud "clink" sound before they chugged their drinks down in one go...

After a couple of drinks later...

Lucifer: *Drunk* Hahahaha....

Mammon: Luci?

Lucifer: Ya know...Your cute, Mammon...The cutest brother I ever had...

Mammon: *Blushes* R-Really? Ya mean that?

Lucifer: *So Drunk* Yes...So reliable...So dependable... I don't know what I do without you! Life was horrible without you~~~! I missed you so much my baby brother!

Mammon: Luuuuuci...You're drunk. Let's get you to bed too.

Lucifer: Hehehe...Okay...I love you Mammon...

The eldest passed out from drinking so much. Sometimes Mammon wished he was somber for him to say that. But hey, he'll take it. It's progress and they have come a long way.

Mammon: I love ya too, ya big baby.
