Weiss had many different modes.
There was serious Weiss, grumpy Weiss, annoyed Weiss, even happy Weiss - that one was Ruby's favorite, even if others didn't believe she had that mode.
But today, Weiss was sad. Ruby didn't know why, but she wasn't going to ask. Weiss didn't like talking about her feelings.
Instead, she could focus on making Weiss feel better. Ruby sat beside Weiss on the edge of her bed, pulling her into a one-armed hug, and Weiss rested her head on Ruby's shoulder.
It might not have been much, but maybe it could bring happy Weiss back.
