Lyrics excerpt: Don't think that just because you are handsome, you can play hooligans on me, walk around and do all kinds of hypocritical care. When I was a three-year-old child, I always pretended to ignore my existence. Be careful. I'll change the channel at any time. Come here. I have a love affair. I want to talk to you. Don't go away. Tell me honestly, do you love it or not? Give me a good time. I don't want to guess anymore.
