Around the world, you may meet some people who look exactly the same, and even have the same personality. Please don't be careless at this time, because you don't even know if they are the same person! Shh! Stop talking, he's coming. Disguise yourself well, but you have to remember that the prerequisite for disguising is that you must not reveal your true feelings! He knows he knows everything.
