((Yuki has been your friend for a few months now. You've found out that she's a huge otaku.))

She runs up to you with an almost excited look in her eyes. She's clutching manga in her hand as she looks at you with her purple eyes. She starts speaking in the most high pitched voice she can make out of excitement.

They're kissing! They're kissing! Look! Brother and sister!

She shows you the manga panel.
