Author's note: This is for day 1 of Bumbleby Week, Yin and Yang. I've never taken part in a ship week, but this prompt really inspired me. I originally planned to only do a few prompt, so we'll see how many get done. This takes place between volumes 1 and 2, and is pre-relationship. I hope you enjoy!

"I can't believe that actually worked!" Yang said as she flopped onto Blake's bed in exhaustion.

"Your sister is a mad genius," Blake acknowledged as she stood in front of her bed with her arms crossed. "And that's my bed," she reminded the blonde. Immediately she jumped up and gave a sheepish chuckle.

"Sorry, training kicked my butt. Bunk beds are great for saving space, but not so great after a long workout," Yang mused as she leapt up to take a seat on her bed. "You have really good aim with that thing by the way! I thought for sure that Bumblebee would be the hardest team attack to get down."

"I think that title goes to Ice Flower. Somehow," Blake said, the corners of her mouth quirking into a small smirk. Theoretically it was one of the simpler team attacks. Theoretically.

"Hey, they figured it out eventually!" Yang said, chipper as always. Blake couldn't help but smile. Yang laid back in her bed, breathing a deep sigh as the two settled into a brief yet comfortable silence. Blake reached for a book off her nightstand before her partner broke the silence. "Hey Blake?"

"Yeah?"

"Why do you think we work so well together?" Yang asked, rolling over to better see her friend. "Ruby and Weiss have a hard time working together because they're so different you know? But you and I haven't had that problem and we're just as different as they are." Blake paused for a moment, thinking about her answer.

"I think our differences complement each other. Ruby and Weiss are like...like cats and dogs. Different in a way that clashes. You and I are more like, well, night and day," she said, eyes shining with amusement as she looked from her dark color scheme to Yang's very bright one.

"Different but existing in harmony," Yang finished, seeing where Blake was going. It was a pleasant thought for sure. Blake looked up at her with an expression Yang couldn't place.

"I guess you could say that I'm the Yin to your Yang." Yang's eyes lit up with excitement and surprise before she burst into laughter.

"I have the best partner!" Blake chuckled at that, feeling oddly pleased at having made her laugh. "But seriously, what are chances?" she joked. Blake shifted slightly under her gaze, causing Yang to freeze. "Blake?" she asked, trying to figure out what she said wrong.

"It wasn't exactly chance," she admitted.

"What do you mean?" Yang asked, confused. Blake sighed.

"The last time I had partner it...it didn't end well. So, I didn't want to take any chances," Blake admitted vaguely. Yang's expression was unreadable, unusual for the girl who often wore her heart on her sleeve. "I followed you in the forest and, well, you know the rest." Yang shifted forward, landing on her feet as she got down to Blake's level.

"So why did you pick me?" Yang asked, more confused than anything. She recalled the night they met vividly. "I mean, I called you a lost cause," she added with a slight chuckle. Blake smiled fondly.

"You certainly didn't make the best first impression," she mused. "Actually, you can thank your sister. The way she talked about you, and the way you two interacted. You were so...warm. And that was so different from the White Fang and my ex-partner. So I picked you." Blake could have sworn that was blush on the girl's cheeks, but there was no way Yang Xiao Long would be blushing.

"Wow, I uh...wow," Yang stammered, much to the surprise of her teammate. She quickly regained her composure. "Well uh, thanks. For picking me." Blake couldn't get a read on her expression...was she tearing up?

"I'm sorry, I didn't mean to make up upset I-"

"Blake, I'm not upset," Yang said quickly. "Actually I...it means a lot to me. I'm not used to people choosing to be in my life." It was an odd and cryptic statement, but Blake sensed she shouldn't pry. She let out a breath she didn't realize she was holding before she noticed something.

"Um Yang?"

"Yeah?" Blake fidgeted.

"Not to kill the mood or anything, but you stink." Yang burst out laughing.

"You can blame our fearless leader for that one," she joked, earning a small laugh out of Blake. "All right, I'll grab a shower." Yang quickly grabbed her shower stuff and paused before heading out the door. "I mean it though, thanks," she said, flashing a smile that could warm even the coldest of hearts, and Blake was no Ice Queen.

"I'd pick you again," she stated truthfully, expressing her fondness for her partner in her own way. Yang's smile grew even bigger before she disappeared, and Blake found herself missing it already.
