Ask: if you are taking requests now I would like the sdra2 boys with a female S/O who has a twin sister and they both have a relationship like Liv and Maddie. They both get into a big fight and now their boyfriend has to comfort them. Bonus points for the aftermath and S/O and her sister make up
Yuki Maeda:
Yuki highly recommends for you to make amends, even if you weren't in the wrong, he still advises you to take the first step
He'll give an honest opinion about whether you're in the right or wrong, but he'll be hesitant about it if he believes the latter
He's scared because he doesn't want to get in the middle and intrude on your relationship, but he also wants to help the two of you make up
"Y-Y/n... You don't have to listen to me, but... I think you should talk to her."
Yuki would cuddle you and reassure you as much as he can, because he knows you'd do the same for him (and you probably have-)
He sets up a fort and movie marathon to help you take your mind off the fight for a bit, and he'll be by your side when you decide to face it
Yuki will try to stay out of the making up event itself, but he'll awkwardly join you if you ask him to
He's extremely proud of you and glad when you make up! The two of you go to the amusement park to celebrate, and he'll offer for you to ask your sister to come as well if you'd like
Yuki is awkward in sibling affairs, being an only child (but also being adopted by Shinji and Setsuka-) but he's trying his best to help you, and his eyes would light up when you tell him he did well
Teruya Otori:
Teruya has had very few, if any, fights with his dad, but he's used to being the mediator between Rei and Tsurugi, so he has a good idea on what to do
He listens to you of course, but also tries to get both sides of the story. If your sister tells him to leave her alone, he won't press
He'll be honest on what he thinks about the fight, but he doesn't think there's a right or wrong with fights, just a difference in opinions
"Neither of ya were wrong...but neither of ya were right either."
If you get emotional, Teruya holds you, not judging in the slightest. The two of you cuddle together until your ready to talk with her again.
He assures you that he'll be there for you no matter what happens, and he's confident that the two of you will get past this
He'll go with you if you ask him, but also wants to give the two of you some privacy. He won't intervene unless things escalate.
Teruya's extremely proud of you when the two of you make up, and he's happy to treat the both of you to dinner
Shinji Kasai:
Shinji would also listen to both sides of the story, albeit stuttering all the while because you're both girls
Even if you're in the wrong, he'll advise you to be the bigger person and make amends
He tries to get both of you to see each other's perspectives, regardless of who's right or wrong
However, he's also patient with both of you. If you need space or affection, he'll happily give it to you. If your sister isn't ready to talk with you, he'll make sure the two of you give her some time
"It'll be alright, Y/n. I'm sure she'll come around, and I'm right by your side..."
Shinji is skilled at handling conflict, but will give the two of you privacy when you decide to make up, still giving you some advice prior. If you'd like him to be there, he'd oblige, but try to take to intervene unless necessary
If one of you tries to walk out on the other again, he'll stop it. The two of you are ending this fight once and for all!
Shinji can only smile when the two of you makeup, turning even redder when you say that it's all thanks to him and his support
Hajime Makunouchi:
He's definitely stressed when he hears about your fight with your sister. Even if you aren't in the wrong, be prepared for a lecture
Hajime doesn't have good experience with families, but he won't let you or your sister abandon each other, especially not because of a stupid fight.
He won't leave either of you alone, making himself a mediator and listening to both accounts. It's a side of him that you haven't seen before...
On the bright side, he'll ease up on his health talks and training. Hajime won't completely let you ditch training, as it could help take your mind off things. Still, he'll gladly hold and comfort you as you express your worries.
"I can talk to her for you if you want Y/n, but it would mean much more to her if you were the one to do it."
He calmly coerces you into talking with her. There was no way he was letting this end on a bad note.
When your actually making up, Hajime would like to be there, but won't invite himself. He'll give the two of you privacy, but would intervene if the two of you still refuse to make up.
It surprises you how much Hajime seems to care about this, but you appreciate his help, even if it can come off as overbearing at times
Yuri Kagarin:
Two lovely women fighting? That won't do!
He would spoil you as much as he possibly can. If you want something, Yuri would buy the whole store. If you were sad, he'd hold you and never let go
He won't take a side, obviously he'll listen to you more since you're his S/o, but if your sister has something to say, he'll listen to her too
Yuri would only give the two of you privacy if you asked him to, to which he'd profusely apologize for overstepping boundaries. Overall, he's more than happy to help the two of you make up
"Everything will be alright, Мой цветок. S/n may just need some time. But until then, I'll always be here~."
He stays neutral for the most part, telling you each how the other has a point. Yuri is a good mediator with fights between women, and would stop himself from intervening as much as he can (If you had a brother, this scenario would be completely different-)
Thanks to him, the fight is handled responsibly and the problem is laid to rest. Yuri is willing to spoil both you and your sister afterwords, but the two of you only thank him, grateful for his help and support.
Syobai Hashimoto:
It depends on how big and serious the fight is
He doesn't know a lot or care much for family, not really having any loved ones before he met you
If she insulted you, he'll tell her to screw off. Syobai isn't one for making up, as fights with his job usually end in bloodshed
If you're in the wrong, he'll tell you. Just because your his S/o doesn't mean he'll automatically take your side
"Y/n, I don't have a lot of experience with this shit. If you don't want to talk to her again, cut the bitch out of your life. If you love her and want to make up, then do it."
Syobai tells you to either talk to her and makeup or get on with your lives, which is still better than what he'd say if you weren't close.
If this fight genuinely upset you, he'll kiss your forehead and begrudgingly hold you until your ready to confront her. He'll claim to leave the two of you alone, but he can't help but eavesdrop.
He feels oddly glad when he learns that you made up with your sister, but he'll completely deny it and claim he doesn't care
Mikado Sannoji:
No matter what, Mikado will always take your side.
He'll listen to your side and will completely take your word for it. She insulted you? He's moments away from summoning flames and threatening her.
He's an orphan, so he has no idea what to do. When Mikado fights with someone, he usually blackmails, begs, or scares them into submission, so he's not good at making up either...
"Y/n, dear...If you'd truly like to make up, I believe you should tell her so."
That's the best advice he can give you, and he wouldn't push you to make up.
Mikado would hold and comfort you as much as you'd like, and would probably avoid your sister. He'll gladly perform some magic tricks to take your mind off the fight!
Mikado won't force anything, letting the two of you make amends at your own pace. He would probably eavesdrop, but wouldn't intervene unless your sister insults you or things escalate
He doesn't expect to feel so happy for you when you make up, but he's happy nonetheless! Your family is the closest thing to a family of his own that Mikado has, so while he puts you first, Mikado is glad that the two of you were able to work it out
Nikei Yomiuri:
You're fighting with your sister?
PLAYER 3 HAS JOINED THE MATCH
Yeah, he's not staying out of it. If you fight in front of him, he'll take your side, and would straight up berate her if she insults you
"What the hell is S/n's problem?? She knows the world doesn't revolve around her, right?"
The two of you vent to each other, cuddling all the while. Nikei is naturally a stubborn person, so you're probably the one who has to mention making up with her before it even crosses his mind.
He has very poor experience with families, but he still wants to try his best to help you. Nikei isn't completely sure what to do, but your bonds with your family mean a lot to you, and he admires that
As a reporter, he is good at hearing both sides of the story, so after the fight dies down, he decides to actually assess both perspectives before making an argument (He most likely ends up taking your side anyway)
When it comes to making up, giving the two of you privacy doesn't even cross his mind (and he might feel slightly offended if your sister suggests it)
Would intervene even if it's not necessary. He means well, he really does, but can be quite short tempered...
In the end, he doesn't really play a huge role in helping the two of you makeup, but he's still glad that you both got past this, and is proud of you for keeping a positive relationship with your sister despite your differences
