It is the exclusive signature of the star to write down the words he wants or maintains for his fans. A star's signature is not meaningful to fans, but only meaningful to fans. Some people don't enjoy the pleasure of idol signature, but enjoy their sparkling appearance on the stage. The signature is like a souvenir they left at home, and they can feel the connection and spiritual support between them and Aidou, which may be the humble place of the star-chasing girl. If they pursue these things too much, they may eventually be too tired to be fresh and take off their meals.
