Indeed it does!

"Okay Rubes, my turn to ask you a question!" Yang chirped and grabbed the book.

"Hit me!" Ruby grinned.

"Which emotions have been shown to draw Grimm the most?" Yang asked Ruby, who considered it.

"Well, they are drawn by negative emotions most, the more negative, the more of a draw they have," Ruby mused and Yang nodded, waiting for Ruby to continue. "Also, it's not just about which emotion you're feeling, but how strongly you're feeling it, for example, a bit of nervousness might draw a nearby Grimm's attention, but outright panic, that's practically a beacon to them. And because fear is the most common emotion felt the most strongly, I'd say fear has attracted the most Grimm over the years."

"Correct, and nicely detailed!" Yang cheered, before presenting her chest to Ruby. "Go ahead and give them a feel!" she offered.

Ren watched as Ruby outright groped Yang, clearly having done it before with how confident she was, and honestly found it hot. The questions continued to fly, and sexy prizes were given out, such as Ruby allowing Ren to touch her too, Yang persuading Ren to spank her as a prize, and Yang kissing Ruby.

"Okay, this is a lot of fun," Ren noted, and Ruby nodded with a grin.

"How about you ask me a bonus question?" Ruby asked Ren, who blinked and nodded, before reading out, "What has been the biggest obstacle to studying Grimm aside from their hostility?"

"...that would be the fact that they don't leave corpses behind, right?" Ruby asked. "They instead disintegrate when they die, so studies can only be done on living Grimm... and obviously, trying to dissect something alive that already wanted to kill you is not a reccomended activity."

"No kidding," Ren replied. "Okay... I'm still unsure what to offer you as a prize, so maybe ask me for something again?"

Ruby giggled as she considered what she wanted.
