"I read this sentence in Keigo Higashino's "The Midsummer Formula", 'No matter what the question is, there must be an answer.' This is my favorite sentence and the most important sentence in my life."

Well, I mean, are you willing to solve this puzzle with me and find the answer?"
Purpose: No matter what the question is, there must be an answer.
