Here it is! Sorry for the wait, I struggled with this chapter, I had zero inspiration. Hope it's not total crap.

"Okay, where do we put the couch?" Mills asked as he and Casey walked into the apartment carrying a large grey couch. Severide scratched his head in thought. Casey rolled his eyes and told Mills to put it down.

"Well, I don't know, where should we put it?"

Shay laughed, "Geez Kelly, I think you really missed your calling. You should have been a decorator," She snapped her fingers at Mills and Casey and pointed to the corner of the room, perpendicular to the fireplace. "Put it here,"

"Yes ma'am," Casey teased as they picked it up once more and put it where it had been said. Gabby, Rafferty and Otis walked in with some more boxes and put them in the bedroom.

By the end of the day, everything was settled, the apartment was completely furnished. Since Severide did not have to be on shift before the day after, he stopped by the police station to pick Erin up. He was leaned against his car when she came out of the building, and she stopped in her tracks, surprised to see him.

"Hey," she said, smiling, giving him a quick kiss. "How come you're here?"

He gave her a lopsided smile, "I've got a surprise for you."

"Oh really?" She cocked an eyebrow. "Should I be scared? Do you have a shovel in the trunk or something?"

He rolled his eyes. "Come on, get in the car," he opened the door for her and she placed a hand over her heart.

"Oh my, such a gentleman."

He drove her to the building of their new apartment and she turned in her seat as he pulled over, both eyebrows raised. He did not say anything and handed her a key. They went up the stairs, down the hall and Erin inserted the key into the lock and pushed the door opened.

"SURPRISE!"

Erin gasped as she saw each person she loved in their living room. She turned to Kelly and hit him in the chest, narrowing her eyes at him. He took her hands and leaned down to kiss her.

"Happy birthday baby," he whispered against her lips. "And happy new apartment."

"You sneaky bastard," she murmured with a laugh, before cupping his cheek. "Thank you."

They pulled away and Erin started by saying hello to everyone there. Shay, Gabby, Rafferty, Casey, Otis, Cruz, Herrmann, Capp, Clarke, Mills, Halstead, Antonio, Ruzek, Burgess, Atwaters, Olinsky and Voight.

Severide watched as she said hello to everybody, and felt proud that she was so happy. He felt a particular tug to his heart as he watched her laugh with his coworkers and friends, as if she had belonged there all along.

Shay pulled him out of his reverie by bumping his hip with hers as she came to stand beside him.

"Nice party bestie," she said, giggling. Shay never giggled. He eyed her suspiciously.

"Are you drunk?"

"I might be a little bit," she admitted. He cocked an eyebrow. "Okay, so I was a little nervous until you guys got here, I wanted everything to go perfectly."

"It did," he assured her, squeezing her shoulder. "It's perfect. Thanks for helping me out."

"You're welcome," she said with a smile. "So, planning on proposing yet?"

He almost spilled the entire content of his drink on his shirt, choking on his sip. He wiped his mouth while uttering out a "What?"

Shay shrugged. "Your guys act like a married couple already. Seems logical."

He chuckled, shaking his head at her. "Shay, we've barely been together six months."

"Life's too short, Kelly. And when I look at the two of you together, all I see is two people completing each other and meant to be together. And, holly hell, I'm gonna miss you as my roommate!"

She suddenly began crying and he chuckled once more, pulling her into his chest and wrapping his arms around her.

The party wore out at about 4 am, and everybody went home one by one, leaving Kelly and Erin alone for the first time in their new home. When Erin closed the door after their last guest had left, she turned to Kelly and sighed.

"You never cease to surprise me, Lieutenant," she murmured as she walked to him, placing her hands on his chest. He covered her hands with his and bent down to give her a soft kiss.

"I'll take that as a compliment," He said, before reaching into his back pocket and pulling out a rectangular black velvet box wrapped with a white ribbon. "Happy Birthday babe."

Erin took the box in her hands and unwrapped the ribbon, letting it fall to the floor before opening the box. Inside of it was a beautiful, yet simple ceramic bracelet with small diamonds aligned in the symbol of infinity. She did not know why, but tears suddenly sprang to her eyes.

"It's beautiful," she whispered.

"Let me," He took the bracelet out of the box and fastened it around her wrist.

"Thank you," she said, meeting his eyes. "For everything. Today was a great day."

He pulled her against him and looked around them, before his blue eyes got lost in her hazel ones. "Welcome home."

Severide had finished his shift earlier than Lindsay did that day, and he decided to watch the football game to pass the time. There was a knock at the door and he stood up, walking to the end of the hall; When he opened the door, he found a distressed young woman on the other side.

"Um, hello?" he said, frowning in confusion.

She fiddled with her hands, avoiding his gaze, "I-is Erin Lindsay here?"

"Uh, no, she's still at work. Can I help you with something?"

Still avoiding his gaze, she shook her head. "No it's fine. I'll come back later."

She was about to walk down the hall when it all came back to him. "Hey, hold on, you're Nadia, right?"

She turned around slowly, her eyes finally meeting his, "She told you about me?"

"A little bit. Do you wanna come inside and wait for her?"

She started fiddling with her bag then and he could tell he was scaring her. He sighed and grabbed his phone from his front pocket, speed dialing Erin ad putting it to his ear.

"Hey,"

"Hey babe," he responded. "Are you gonna be home soon?" he asked, not taking his eyes off Nadia, who had started to rock herself in the middle of the doorway.

"In about ten minutes, we've just wrapped the case."

"Listen, Nadia is here, she wants to talk to you. Can you tell her it's okay for her to wait with me or something?"

Her tone changed immediately. "Put her on the phone please,"

He extended the phone to Nadia, "It's Erin. She wants to talk to you." She hesitantly took the phone from him and put it to her ear.

"Hello?"

"Nadia, it's Erin. Listen, I'll be home in a little bit, okay? Go in with Kelly, you've got nothing to worry about. I'll be there soon."

"Okay."

Once she had hung up, Kelly opened the door wider and stepped aside to let her come in. He closed it behind her and turned around.

"Let me take your coat," he said, making a move to pull it off her shoulders. She flinched away and he raised his hands slowly. "Sorry, my bad."

"Could I have some water please?"

"Sure," he lead her down the hall and poured her a glass of water.

"What has Erin told you about me?" she asked after taking a sip, looking up to meet his eyes. He leaned against the counter and laced his fingers together.

"That you reminded her a lot about herself back in the day. And that you were a strong kid who just needed help."

Nadia nodded as she absently ran her finger on the rim of her glass, over and over again. She looked around the living room. "So you guys live together?"

"Yeah. We moved here a couple weeks ago."

"Right," She shivered and scratched her arms up and down. Kelly did not know what to do. He wanted to help her but obviously she did not feel comfortable around him.

"Um, do you need anything else?"

"No, I just need to see Erin. When will she be here?"

As she spoke, the door opened and closed and a few seconds later, Erin appeared at the end of the hall. Nadia stood up from her chair and rushed to her, pulling her into a bone-crushing hug. Erin was taken aback but wrapped her arms around the smaller girl, sharing a look with Kelly over her shoulder. He decided it was best he went to the bedroom to give the two women some privacy.

"What's going on, Nadia?" Erin asked, pulling away. Tears filled Nadia's eyes as she tried to speak.

"I saw some of my friends from the streets. I felt lonely, you know? So we got together, but they started to take some dope and they asked me if I wanted some, they insisted and-"

"Tell me you didn't take it," Erin said with serious eyes.

"No, no, I wouldn't, but it's hard. I just thought I would come down here and talk to you before doing something stupid."

Erin cupped her face, "You were right. This is exactly what you should have done, okay?"

The girl sniffled as Erin wiped her tears away. "I'm sorry for barging in like that."

"Don't sweat it. How 'bout you stay here tonight? I have the day off tomorrow, so we'll spend it together, see if we can land you a job. What do you say?"

Nadia nodded frantically. "Okay, alright."

Erin rubbed her arms up and down. "Good. Let me show you the bedroom."

They walked down the hallway which led to the two bedrooms and bathrooms, and Erin pushed the door open to the guest bedroom, letting Nadia in first. As it hadn't been used yet, the bed was bare without any sheets or blankets. As if on cue, There was a knock and Kelly popped his head in the partially open door. He opened it wider and came in.

"Thought you might need these," he said, gesturing to the sheets and blankets in his hands before setting them on the bed.

Erin smiled, "Thank you."

Once she had Nadia all settled in the guest bedroom, Erin changed from her work clothes and joined Kelly on the couch. She kissed his cheek and snuggled close.

"Is she okay?" he asked, rubbing is hand up and down her back. She looked up at him and slightly turned to face him.

"She will be," she said. "Is it okay with you if she stays here for a little while?"

Kelly nodded and kissed her forehead, "Of course. As long as she needs."

She cupped his cheek, blinking back tears. "How come you're so good to me?"

He chuckled and pulled her into his arms. The next morning, Severide was making breakfast when Nadia got up. She walked into the room wearing one of his Chicago Fire Department sweatshirt that Erin must have lent her.

"Morning," he greeted with a smile from his spot at the cooking station. She simply waved awkwardly and sat on one of the stools at the counter. "How do you like your eggs?"

"Thanks but I'm not hungry," she said quietly. "Where's Erin?"

"She's gone grocery shopping. She should be back soon."

She nodded, fiddling with the sleeves of the sweatshirt. The next few minutes were spent in silence, at the exception of Kelly whistling some tune. Once the scrambled eggs were done, he grabbed a plate from the counter, emptied the frying pan in it and grabbed a fork and knife before depositing the plate in front of Nadia.

"I hope you like scrambled eggs," he said with a wink. Her stomach gurgled and she blushed, whispering a quiet thank you before starting to eat. He poured her a glass of juice and resumed to reading the news at the opposite end of the table.

"So you're a firefighter?" she asked, glancing up at him. He was surprised to hear her talk to him.

"I am. Rescue squad Lieutenant," he said nonchalantly.

"What's a rescue squad?" She asked then.

"Rescue squad is specialized in rescuing trapped people. In cars, water, industrial machines. So my team and I do all of those things."

She lifted her eyebrows. "So you don't deal with fires?"

He nodded, "Yes we do. But when there's a car accident, we mainly focus on freeing the victim from the car and then the firefighters from Truck usually do the rest."

"It must be scary, dealing with fire."

He shrugged. "You get used to it. You have the adrenaline pumping and this desire to save people. I don't see myself doing anything else."

She nodded silently, before going back to her book. He hadn't even noticed she had been reading a book. Curiosity getting the best of him, he asked what book she was reading.

"To Kill a Mocking Bird," she answered with a smile. "It's one of my favorite books. I often spent time reading in the library at the clinic. It killed time, and I started enjoying it."

Kelly nodded. "One of my colleague's wife works in a book shop. I can ask her if they're looking for somedy, if you'd like to work there."

Nadia's eyes widened. "A bookshop? I'd love to."

"Then I'll ask her."He said as he observed her. She seemed so fragile but strong at the same time, after all she had been through. "You know you can stay here as long as you want, however long you need to get back onto your feet."

"Thank you," Nadia said sincerely. "Erin is lucky to have you."

He shook his head, his lips spreading into a smile, "I'm the lucky one."
