Black Butler Preference (and maybe Imagines)

Preference: Break Up

Ciel: It would actually take him a moment to realize that your actually leaving. He'd be sitting by his window after your big argument looking totally calm, but as soon as he heard the door to his study open, he'd understand just how royally he had fucked up.

Grell: He wouldnt dare show you how hurt he was about it, he'd act like brushing it off like he does with Sebastian all the time. But behind a straight, angry face, he'd be crying on the inside that the best thing was walking away from him.

Sebastian: Despite the emotionless face he always puts up, the fact that he had hurt you so much that you were leaving, would tear him apart. Though, he wouldnt lash out and kill anyone, break anything, or scream. Instead he'd beat himself up about it, blaming anything and everything.

Undertaker: Underneath those bangs, and his creepy facade, if you two broke up it would absolutely tear him apart. He would silently cry because, he had actually found someone to love him for everything he was and you two had ended because of something so stupid.

Finny: Now no one would suspect Finny to be an aggressive person, but to have his everything leave him would cause an emotional outbreak in him. He'd throw anything he could break to try and calm himself.

Bard: This one here would be one of the calmer ones. Even though you two just broke up, he'd remember your voice telling him to not get so angry at things, just take a calming route. So he'd sit in his kitchen, head in hands, pulling at his hair and just wondering where everything went wrong.

Mey-rin: Mey-rin would cry, she'd cry and beg to nothing that the person that saved her from herself, her angel had left her. She honestly wouldnt know how else to react after that though. She might throw things, or scream, or cry into her pillow until it was soaked, but all she really wanted was to get you back.

Ash: He would honestly have a very stoic face until the door slammed shut behind you. It would cause him to jump, kicking him back into reality for a moment so he could just take in the whole situation. After, he'd punch, kick, throw anything he could reach. Yanking at his white hair and blaming himself to no end.

Pluto: He would just need to blow off some steam, calm down after all the arguing. So he'd run through the forest, the city, pretty much anywhere. Repeating the rights and the wrongs of the fight until he'd come to realization of what just happened, that you two had broken up.
