That was photo evidence and just in case with Naachan and even photos on Shida and her boyfriend. There are so many pictures on Fuuchan and Zuumin on Fuuchan's blog that she is accused for being one of the five culprits which makes this rumor even more silly. We heard from her older brother that she was bullied. That's all you got as an answer. Bunshun couldn't come up with something better. A picture is worth a thousand words.
