Di Qiuren heads the Astronomy Club and leads its members on a hunt for aliens, though so far every search has come up empty. The joke is that he is looking in the wrong direction. Every member of his club is secretly an alien, disguised as an ordinary club member. To keep their true identities hidden, the aliens try to study and make sense of how earthlings behave. Meanwhile, Qiuren keeps up his determined search right alongside the very beings he is trying to find. The result is a comedy of school life, built on the gap between a club president who never gives up the chase and the aliens working to pass as human.
