Doraemon: There's Something Wrong with Fat Tiger's Song

Fat Tiger is going to have a concert again. This time, he didn't force everyone to stay. He only asked Doraemon: Where did I sing wrong? The future detector discovered that his singing contained an abnormal structure that could not be explained by ordinary acoustics. What's more troubling is that this sound seems to really affect people's emotions and judgment, and the 22nd Century Database issued a restricted warning about it. When an old recording of Fat Tiger is taken away by a stranger, things get completely out of control. For the first time, Fat Tiger began to doubt: When someone says they like her, do they really like her or are they affected by his voice?
