A/N: Could be a one shot, could have more chapters.. depends on whether anyone wants to read it. I know this has been done countless times with Marsan, but once I got the idea in my head, it wouldn't go away. This is the first fanfic I've ever written, and the only reason I'm posting it really is because I want some tips. I know this isn't the best, but I would appreciate it if you'd read it and review. Let me know if you want more, or if there's something I can improve on... Thanks!
I DON'T WANNA LOSE YOU
The cold Chicago wind stung his eyes and his skin as he ran through the city to find her.
Her. Susan.
His best friend, his confidante, the one person he knew he could trust, and she was leaving. She was leaving him. He still couldn't believe he was running after her. He would never have done anything like this for Jenn. He loved Susan, and he was kicking himself for not telling her sooner. He'd only realised his feelings for her in the last couple of weeks, but it felt like he'd loved her forever. He was sure she loved him too, but if he didn't catch the train, he may never know.
He'd finally reached Union Station. He stepped out onto the platform, but he couldn't see her anywhere. He breathed out slowly, and he could feel the tears at the back of his throat as he realised he was too late.
"You lookin' for the chief?" Mark turned at the sound of a voice. There was a man walking passed him. Mark watched him. "They moved her to number six!" he called over his shoulder as he walked away. Mark turned around, looking to the next platform.
She was there. His breath caught in his throat and he could swear his heart stopped.
"Susan!" he yelled. She hadn't noticed him. He ran back out the door and onto the next platform. He called her name again and this time she turned to look at him. She raised her eyebrows in surprise.
"Mark?" she questioned as he moved closer to her. "You came to say goodbye?" a grin appeared on her lips.
"Stay." he shook his head. He was breathless after running so far. He was leaning against the train, clinging to it as though he would collapse if he were to let go. "I want you to stay."
Susan stared at him, stunned.
"What..?" was the only word she could find. "Mark…" she started, a frown appearing on her lips.
"Wait," he began, "… I love you.." he blurted it out, not wanting to tip-toe around the subject, they had done enough of that already. "I think I always have.. And I'm stupid for not saying it sooner…" he trailed off.
Her mouth opened slightly, she was surprised. She could feel the tears coming, but she wouldn't cry, not in front of him.
"Oh, Mark.." she said, trying to compose herself. "You have no idea how long I've waited for you to say that.." she confessed and a hopeful smile appeared on his lips. "But, I don't know if I can stay." she added sadly.
His smile disappeared.
"What?" he refused to believe what he was hearing.
She stood there, helpless.
"Susan," he started, "Right now I need you more than Susie does." he stopped, did she really need to hear this? "Chloe's happily married now, and she is Susie's mom. You need to accept that." he told her, and felt an ache in his heart at the hurt evident in her eyes.
Susan's eyes were brimming with tears now.
"Are you really asking me to choose between you and Susie?" she asked, a tinge of anger in her voice. Mark shook his head with a sigh.
"Susie doesn't need you like she did before.." he said, "You need to trust your sister to do the right thing now… and move on with your life."
Susan shook her head. She didn't want to believe what he was saying, but she knew he was right.
"I do love you." she said, desperately. "I really do. But I don't think I can move on from this."
"We can move on from this together, Susan. You have to trust me. I would never hurt you." Mark said, a small smile graced his lips. "Please, stay."
She stood there, trying to make her decision. "I don't want to lose you. We are perfect for each other." he said, practically begging now. "I know you feel the same."
Susan looked from Mark then back to the train again, before yelling to the man on the train: "Can you pass me my stuff please?"
She grabbed her luggage desperately, as the train pulled out of the station. Susan was breathing heavily as she looked at Mark. He had the goofiest grin on his face. He ran to her and wrapped his arms around her, he didn't want to ever let her go. He pulled away slowly, reaching one hand out to cup her face. His thumb stroked her cheek while his other hand found it's way to her hair, brushing it out of her face.
She exhaled slowly, relaxing at his touch. His lips found hers and they shared their first kiss.
