Bumbleby

Bumbleby is the femslash ship between Yang Xiao Long and Blake Belladonna from the RWBY fandom.

Canon
Their first interaction was in volume 1, chapter 3, where Yang wanted to help Ruby make new friends. Blake first seems to have no patience with the 2, only wanting to go back to being alone. Yang says that she's a "lost cause", although when they're picking partners, she seems happy to be Blake's partner. Even though Blake is known to be the cold and mysterious person in the team, Yang makes her smile on several occasions after they become partners.

In the episode Burning The Candle, Yang tries to get Blake to relax from investigating the White Fang and just attend the dance. She confronts her and actually got her to go after relating to her and showing her that she cares about her a lot.

In the episode Heroes And Monsters, Yang chooses to go find Blake other than her missing sister. When she finds Blake, Adam says that he'll "Destroy everything that she(Blake) loves". Then when Yang arrives, he points at her saying "Starting with her". Blake then shows a horrified face, which confirms Adam's assumption. Yang get's angrier than she ever has in the entire series and get's her arm taken off when she recklessly charges in.

Fanon
In the episode Burning The Candle when yang tries to convince Blake to come to the dance, she hugs Blake and says "And if you feel like coming out tomorrow... I'll save you a dance". Yang is always known for her puns and this could be referencing coming out as in revealing your sexuality.

In the episode Downfall, Blake is finally reunited with her team after running away at the Fall Of Beacon. Despite being in a room full of people who also haven't seen and worried about her, the only name she says is Yang's. This helps the fact that Blake and Yang really did miss each other equally as they both almost breakdown just talking about each other when they're separated.
