That's an answer not good enough for Erwin. He looks around the room and he needed just seconds to figure out what must've happened here. Levis anger, the fact that he hurt his hand by punching something hard and the shattered vase...This all are his witnesses.

"Levi. What have you done?" The volume of his voice increased rapidly, so as the commanding tone kicked in.

"What I had to." Levi's gaze is still focused on the ground, his voice bare of any strength. He can't face Erwin. Not after what he had done. Erwin is unpredictable when it comes to Nina and her well-being. Just like Levi himself. He will be lucky if Erwin just yells at him.

"What did you do to her Levi?! Tell me!" And there's the yelling Levi expected. As if he has to justify his actions to him. That's none of his business. Nina is Levi's girlfriend, not Erwin's! Or at least...She was. Levi is expecting that Nina doesn't want to see him ever again after this show. And when he thinks back to the last months, Erwin would be a more suitable partner for her. She deserves something better than the fucked up bastard Levi is.

"I chased her away. She will probably never come back to me after all the things I said to her. So you have her now all for yourself." Levi mocked on him. Now, that Levi is out of his way, Erwin maybe will find the luck together with Nina that he wasn't able to find. But Levis thoughts and words were cut off as Erwin's fist hit his face, hurling him to the ground in a loud impact, causing the shelf to shake while Levi tried to grab it for support. That's the least Levi deserves. With an evil grin, he remains on the ground, not even looking up to Erwin or trying to cover the huge amount of pain in his face. Erwin hurt his hand with this unforeseen and impulsive act, but he couldn't care less. What Levi did to Nina was inexcusable! And he would deserve far more than just this one punch.

"How dare you to do something that cruel to her? How?! Is this your idea of "protecting" her?" Erwin yelled at Levi, his fist hitting the wall beside him to release his tension instead of beating the shit out of Levi.

"How I dare? Isn't that obvious? Because there's no other way to protect her from getting hurt even more. As long as she's by my side, Petra won't stop with her actions. She will go after Nina until she achieved her goal to make Nina commit suicide! I can't let this happen! I won't let this happen. So I chased her away with words that will make it impossible for Nina to love me ever again. There's no other way..." Levi's voice was low, broken. He's still suffering from the last time he dared to open his heart to a woman like this and before Petra appeared to ruin his luck. But that's no reason to act like a heartless coward!

"There's always a way, Levi! You are just too scared to use your head for something useful once instead of how to remove wine stains from a white rug!"

"Its too late. What's done is done. Leave me alone." Levi growled, still in a low volume. He's suffering from his own actions, yet, he claims it as the only possible way to protect her. Erwin can't stand here any longer and let the things develop like they're doing it right now. With big and fast steps, he leaves the living room for his bedroom. He throws the towel away and grabs the first clothes that came into his range. In two minutes he was fully dressed. He left his bedroom again as he slams his door shut loudly behind him. in the meantime. Levi had started to collect the shards from the ground before he looks up at Erwin, following all his actions.

"What are you up to Erwin?!" His eyes widened while he watched Erwin putting on his shoes and jacket.

"What does it look like? Fixing what you messed up! Don't wait for me!" Erwin grabs his keyring to leave the apartment without looking back. He ignored Levis protesting yells behind him as he runs through the staircase, down into the underground car park to jump into his Audi to drive to Nina's place as fast as possible. While the engine started to growl, he pushes the accelerator down to the limit, making the tires scream and squeal as he left the garage far above the allowed speed limit. Erwin's phone buzzed the whole time with incoming calls from Levi while he drives down the street in an incredible speed, but Erwin just took his phone and turned it off before he threw it on the ground on the passenger side. Luckily it's already late, so there's not much traffic in the streets at this hour. And thanks to this, he arrives at Nina's place in a way shorter time as usual. He quickly searched for a free place to park his car and then he ran to the building as if the devil was chasing him. He pushed the doorbell to her apartment over and over again but he received no response. Now he's really starting to worry. The first thing that comes to his mind to get into this building was to ring on a different bell. When the door finally opened, he ran through the staircase, taking 3 steps at once and ignoring the person on whom's doorbell he'd rung. When he finally reached the top floor, he bangs the door loudly with his fist.

"Nina! Nina! Are you there?! It's me, Erwin! Please open the door!" He yelled desperately. For a few moments, he heard nothing. Then, a silent rustling sound from the other side of the door was heard before it opens wide enough to peek through. But all he could see was half of Nina's face. She cried. A lot. He didn't even need light to see this.

"Please, Nina. Let me in. I need to talk to you. Very urgently. Please." He pleaded, his heart pounding in his chest from shock about her horrible state. She nods slightly before she finally opens the door. He quickly enters into the dark apartment and closed the door behind him before he turns around again. But he didn't come far as he suddenly feels a tight embrace around his back when Nina cages him in her arms, pressing her face deep in his chest and fisting the jacket on his back as she started to cry again in never known agony. Erwin feels himself close to the edge of crying too by the view of his favorite girl in this state. It hurts him so badly and all he could do right now was hugging her back and letting her cry as long as it lasts. Her desperate screams of pain won't stop. She whined Erwin's name over and over again, in hope he could do something to make the pain disappear. But all he could do right now is to offer his broad chest for her to cry her eyes out until she will calm down. He hates Levi so much for what he did to Nina. But knowing the reason why he did this caused his hate to subside again. But Nina deserves to know the truth.

That's why he's here. And of course to be here for her as a friend, to be here when she needs him the most. To give her someone to lean on when she feels the whole world against her. By now, Erwin finally understands the whole extent of the love she feels for Levi. He means everything to her. He was, or still is, her entire world. And that makes this situation even crueler. Almost ten minutes pass by while they both just stand in the middle of the hall, tightly embraced and with Nina crying. Even if her screams turned into muffled sobs, this starts to get tiring, even for Erwin. He suddenly lifted Nina up to carry her into the living room, where he sits down on the couch with her in his lap. Now he can comfort her properly as he rubs her back slowly up and down while pressing her head to his shoulder with the other one. Her shoulders still shaking violently from her crying and his shirt is soaked from her tears, but he senses that she's about to calm down a little. Erwin cups her face in his hands, wiping her tears away with his thumbs and looking into her swollen eyes.

"Erwin...." she sobbed desperately.

"Shhhh...Don't talk yet sweetness. It's better if you just listen." She nods a few times in response before she cuddles up to Erwin's shoulder again, still breathing heavily and probably still close to the edge of crying, but he just has to tell her the truth. The reason why Levi did this to her and why he's acting the way he is. Erwin continues to stroke her back up and down in slow and gentle movements before he starts his explanation by talking into the dark nothingness before him.

"Nina, first of all, I want to let know that Levi would never hurt you intentionally." He assured her while putting his hand on her shoulder and pulling her body closer to him.

"I doubt that..." She replied bitterly. "His words were pretty clear."

"I know, darling. But please let me explain. For his and your own sake please don't give up on him yet. Levi usually has a hard time trusting other people, he tries to shut others out because deep within he's afraid of getting hurt. You need to trust me and believe me when I say, that he's feeling miserable right now and regrets his words to no end. Levi is really shy when it comes to honest feelings. He's most likely afraid you hate him now and don't want to see him ever again. He said all these mean things to protect you from more harm. Even if his way of protecting the ones he loves is kind of weird and twisted. And now, for the first time after a very long period, he found someone he would trust with his own life, and this special person is about to get hurt. For the same reason, his former love got hurt as well. And this reason bears the name Petra Ral." Erwin knows Levi for quite a while by now and knows his antics and the way he thinks. The least Erwin can do is to enlighten Nina's mind about it.
