Does fairy exist? Does anyone in the world really have magic?

It exists, just like you said. It exists in the heart of everyone who believes in her. Don't say they are superstitious, that's their spiritual sustenance, they spend money to buy inner peace. If your parents feel uneasy, the effect of letting them see a psychiatrist will definitely not catch up with the effect of seeing a nun, and the fees of psychologists will definitely be higher.
