Only Poor People Can See Aliens

On the day when the mortgage deduction failed, Zhou Yan discovered that there were no passengers on the subway. After the money arrived, the other party became normal again. After collecting money and refunding money several times, he confirmed one thing: poor people can see aliens, while rich people will forget them along with the related memories. The only stable thing about this ability is that his income is not stable. But his mother was waiting for money to treat his illness, and his alien friend who had saved him was waiting for his help. He has to earn money and he has to remember. Others worry that their friends will not recognize them after they get rich, but Zhou Yan worries that he will forget his friends first.
