Midnight Diner [Echizen Ryoma X Sato An]

...But we all know you absolutely can't count on Echizen Ryoma to make a post explaining what happened. There's about an 800 percent chance that won't happen. So poor Sato An, after finally figuring out the whole story, rushed to the BBS and posted a clarification. The title was, "The truth is, Echizen's big sister used his account. Can you all calm down?!" But the people in the thread showed absolutely no mercy and replied in unison:

"Hey... Do you guys believe that? ╮(╯▽╰)╭"

"You tell me w"

"You tell me w"

"You tell me w"

"You tell me w"

"You tell me w"

"You tell me w"

I finally understand firsthand what "you brought it on yourself" means...
