He didn't care when she made fun of him afterward, or when she put her dirty boots all over the interior of his car. Because she was Mikasa, his best friend. Plus, she looked damn good in those boots, and everything else.
He wondered what she would be wearing as he drove over to her apartment, wearing the matching ring she gave him as his fingers gripped the steering wheel. His was a thick silver band with a small butterfly cutout, and hers was the fragment on a smaller ring. 
She also had a butterfly tattoo on her lower back, which Eren saw as she turned after opening the door to her apartment. She was wearing low-waisted black cargo pants and a tight-fitting black crop top, which exposed the wings of the butterfly extended from the small indent of her back that curved inward perfectly, no doubt from all the boxing workouts she had been doing lately. 
She sat down on her black couch, leaning forward to the glass table in front of her where she had weed and rolling paper laid out. "Come sit," she said, gesturing next to her as she placed the green leaves in a grinder. Eren watched her delicate fingers take the weed out, placing it in the wrapping paper before she rolled it up. Then she moved to his favorite part, licking the edge of the paper by running her tongue against it gently before she closed it. She took a lighter out, pressing the blunt to her lips and attempting to light it. Her red acrylic nails got in her way as she flicked it over and over again, missing the tab every time.
"I got it," Eren said, getting frustrated with watching her. He took the lighter from her hands, making their fingers brush against each other slightly. He lit her joint, making the paper burn orange and causing small embers to float away.
"You always do," she said as she took a deep inhale, pushing it out a few seconds later.
"Is this what you invited me over here for?" Eren laughed. "To help you light a blunt?"
"No," she smiled, taking the weed pinched between her index and middle finger and sliding the end between his lips. "Maybe." He wrapped them around the grey paper gently, hesitantly.
"Come on," she coed. "We haven't smoked together in forever."
He knew that, but it was for good reason. The last time they spent the day together, eating and walking around some random park for hours. Mikasa overdid it for the first time ever, nearly greening out. He carried her home in his arms, laying her down in her own bed. When he tucked her in and turned to leave, she asked him to stay. He hesitated, looking down at her through hazy eyes as she pulled him down towards him. He almost stayed, almost.
He rolled his eyes, taking an inhale and eliciting a cheer from her. A few more later they were both nearly passed out, Mikasa leaning on Eren as his back pressed into the corner cushions of the couch.
"I feel so-- tired," Eren slurred, running a hand through his hair. 
"You're not tired, you're high," Mikasa laughed, sitting up. "We can go lay down if you want."
"Yeah," Eren said, dragging out his speech. Mikasa stood up, holding Eren's hand and helping him up. He trailed behind her as she took him to her room, staring at her tattoo again. He laid down on her bed and she joined him, relaxing on her back and looking up at the ceiling.
"This is nice," Eren said, his blue eyes sliding over to her side profile. Her long black lashes rested against her closed eyes as she hummed in agreement.
"Smoking always relaxes me," she breathed, placing her hands behind her head.
"No, I mean just us hanging out, no one else," Eren said.
"Oh, yeah," Mikasa agreed, looking over at him. His eyes were already on her, meeting her grey ones.
"You tucked your hair behind your ears," Eren observed. "Looks good."
