Oh shit. You've pissed off Yuki.

Do you want your possessions identified?

oh yeah this is part of the whole Tsuruya x Kyon doujin. That was pretty funny and cute. Lol the forehead is Tsuruya's ero spot haha ><

What's the name?

"The Secret of Tsuruya-san" I believe it was called.

To be fair, this isn't Yuki going Yandere per se. Rather, it's Yuki going "Once Haruhi realizes Kyon is in love with Tsuruya, the universe is going to explode."
