Here's an edited and proofread version of the text, aiming for a more polished romance-mafia novel style:
Samara's entire life, this was the first time she felt such trepidation. Since she was orphaned and her parents murdered, she had promised herself she would be brave. Yet, at this very moment, she trembled for her life.
She had joined Senza Pietá to find her parents' killer. She was also well aware of their mafia boss. She had heard the whispers: he was ruthless, short-tempered, and utterly merciless, whether ending the lives of enemies or those who simply displeased him. And now, Samara found herself with one foot in the grave, having punched their universally feared boss just last night.
It wasn't my fault, Samara fumed inwardly. If that man wasn't so meddlesome, I wouldn't have punched him. Besides, he was going to let Gustavo do indecent things to me. He deserved that punch.
"Do you know this is the first time Il Capo has ever come to this club?" Samara's manager said, walking ahead of her.
"I-Is that so..."
"I have no idea why our boss personally came to this club for you, but I would regret it if you did anything wrong to Il Capo and he punished you. That's the only reason Il Capo would be here."
"Do you think, manager, that if I go into your office, I won't come out alive?" Samara asked as they arrived at the manager's office door.
"I can't say, but I know Il Capo. For anyone who wrongs him, death is the only payment. Go on in."
"You-You're not coming with me?" Samara asked, startled, as their manager shook his head.
"Il Capo only needs you. It's not necessary for me to come in too. Go on, and if you know how to beg, do it now," her manager said before leaving her.
"That man is so sensitive. Just a punch and he's going to punish me with death? Couldn't he at least torture me first?" Samara grumbled, staring at the door behind which Elijah waited.
"Why should I beg? If he wants to kill me, then so be it. I'll die without begging any man, even if he's a king." Samara declared, composing herself before opening the door.
Upon entering, she immediately saw Elijah, his back to her, facing their manager's desk. Samara steeled herself until Elijah turned to face her, holding a folder.
"It's you," Elijah said coldly before walking to the sofa and sitting down.
"Come here. I'm not the one who will adjust to approach you," Elijah commanded, causing Samara to subtly roll her eyes before walking closer to him.
"Do you remember what you did to me last night? You punched me, here in my freaking, fucking face," Elijah stated plainly as Samara stood before him, pointing to the spot on his face where she had struck him.
"It only happened last night, so of course, I remember," Samara couldn't help but retort, making Elijah fix his gaze on her.
"You won't beg for your life? I can kill you right now for disrespecting me as your boss," Elijah said with chilling coldness. Samara couldn't stop her true nature from surfacing.
"I won't beg for my life because it's truly your fault, BOSS, that Moretti escaped. And if you're going to punish me because I punched you, then just kill me," Samara bravely declared. Elijah rose from his seat and approached her, his eyes unwavering as Samara stood her ground.
"You are the fucking first person who has disrespected me like this, you even punched me. Do you know I couldn't sleep because I kept thinking about what you did?!" Elijah roared, barely an inch separating them.
"And what did you do to me?! My heart keeps fcking pounding thinking about your punch, and I don't fucking like it!"
"Why are you blaming me? How would I know why your chest is pounding just because of my punch?! And I'll repeat it, okay, it's your fault I punched you because I was about to kill Gustavo, but you interfered?!" Samara snapped. Instead of getting angry, Elijah stared at Samara's face, inches from his own.
"Just kill me and get it over with, because I will never beg for my—"
"—What's your name?" Elijah interrupted, making Samara frown at him.
"Why are you asking me? Wait, do you need to know my name before you kill me?"
"What's your name, tell me," Elijah repeated, causing Samara to sigh.
"Samara Cortez, Your Excellency. Now that you know, do what you came here to do," Samara said, closing her eyes, awaiting her death.
She didn't want to die, but she also refused to beg.
Elijah clutched his chest as his heart pounded, his eyes fixed on Samara's beautiful face. This was the first time he had felt such unknown emotions towards a woman. He should have been punishing her with death, yet that wasn't why he had come to the club.
"I'm not done with you, woman," Elijah merely said before walking out of the office, leaving Samara bewildered and opening her eyes, confused by Elijah's sudden departure without doing anything to her.
"Is the mafia boss of Senza crazy? But at least I'm still alive, how lucky," Samara cheered, breathing a sigh of relief as Elijah disappeared from her sight.
Elijah walked straight out of the club, his right hand still pressed against his chest. He had felt his heart pounding since last night. He couldn't understand why he was so affected by Samara's punch, and by her presence.
"What the fuck is happening to me?!" Elijah muttered to himself, utterly confused.
As he exited the club, Taddeo arrived with Lorenzo, who had just stepped out of a car. Both immediately noticed him and approached.
"Il Capo, I know I said it was okay to punish Silas, but consider her since she's an excellent asset. I'll just talk to her, but have you already killed her, Il Capo?" Taddeo asked Elijah in greeting. Lorenzo then noticed something.
"Why are both of your ears red, Il Capo? Are you okay?" Lorenzo observed, making Elijah instinctively touch both ears.
"D-Don't mind my fucking ears," Elijah snapped, quickly leaving Lorenzo and Taddeo, getting into his car, and driving away.
Lorenzo and Taddeo were left confused; it was the first time they had sensed even a hint of disarray from Elijah.
"What happened to Il Capo?" Lorenzo asked. Taddeo quickly entered the club.
In the hallway, Taddeo and Samara met, and she smiled broadly at him.
"I'm alive, Taddeo," Samara cheered. Taddeo pointed at her, surprised.
"Il-Il Capo didn't do anything to you?!"
"Why do you sound like you'd rather Mr. Penelton do something to me, huh?" Samara complained instantly, causing Taddeo to quickly approach her and examine her from head to toe.
"Did you beg Il Capo, that's why he didn't punish you?"
"I didn't beg. We even argued."
"What?! You argued with Il Capo, and you're still alive?" Taddeo asked, startled, as Lorenzo also arrived.
"Do you really want Mr. Penelton to kill me? Even if you were here, you'd just let him kill me, wouldn't you?! Have I contributed nothing to you, huh?!" Samara growled.
"What you said was right. He even said last night that he would let Il Capo punish you and even volunteered to bring you to Il Capo," Lorenzo reported with a grin, making Samara scowl at Taddeo.
"You idiot, Salvatore! Sometimes your tongue just can't stop talking, it'll get me in trouble," Taddeo retorted, only making Lorenzo grin wider.
"Then what was the point of asking you for backup if you were just going to let Mr. Penelton punish me with death?" Samara growled, making Taddeo smile at her.
"What are you talking about? That's why I hurried here to help you. But why didn't Il Capo do anything to you?" Taddeo asked, wanting to know why nothing had happened to Samara.
"How should I know? I even agreed to let him kill me because I punched him, and then he suddenly left. The important thing is, I'm alive," Samara declared, smiling as she left Taddeo to return to cleaning the club.
"Someone disrespected him, yet he spared her? Then why did Il Capo come here?" Lorenzo wondered aloud. Taddeo also couldn't think of any plausible reason.
