You call it stupid, but it seemed to be highly effective. Plus I reckon Yuri has too much pride not to tell the truth. If she was later proven wrong, she could hardly call herself Miku's biggest fan and the only one worthy of Miku's love. That's how it goes with obsessed people. Think of the pitiably infamous War Thunder: miserable people are leaking classified information all the time just to prove they know something their peers don't know. Yuri will gladly use any opportunity to show she possesses the most Miku information.How stupid must you be to challenge someone to a quiz for which you don't know if the answers are right?
