Scaramouche break up is because his own insecurity, he felt he never good enough so he decide to break up but he regret his own decision. But, he wont admit it if he still miss his ex and end up drinking to forget his regret. He just dont know how to treat his parter better end up being harsh and toxic. He didnt want to look pathetic thats why he decide to pretend didnt care even thought deep down his heart he want to back with his ex.
