First, touch the bottom with your finger. Let's see if we have a spark. It's real! How does it work? Look, it doesn't light up if we aren't touching. See, if I touch you... 'cause right now we're not touching, Let's bring it closer. But if I grab Gaogao's hand... I'm so bright, bright, bright~ Amazing... It lights up because we have feelings for each other. -This is too cool. -Have you all seen this yet? This light tests whether I have feelings for Gaogao. Gaogao, come. Why is it like this? We're not touching each other now, but if we have feelings.... What...? Is it not? Gaogao, I have feelings for you. Ahhhh! I got tricked!
