Milky Way Customer Service Department

Shen Zhongyi, an ordinary high school student, accidentally discovered that the girl he liked was an alien and also a staff member of the Galaxy Customer Service Department. The department responds to various incidents caused by tourists (aliens living on the earth), and "solve" the problem with the people who now are involved (delete memories, tamper with memories, and even destroy their bodies). In order to avoid being wiped out and losing the memory of getting along with her, Shen Zhongyi started a job career in the customer service department of the Galaxy, which came with a lot of danger.
