Di Qiuren is hunting aliens while surrounded by them, completely oblivious, and the comedy lives in that gap between his earnest obsession and their panicked, hilariously wrong attempts to act human. Every scene is built on the aliens constantly breaking character in small, specific ways, they don't understand Earth customs, they misread social cues, they panic when Qiuren gets close to the truth. It's a show that trusts you to laugh at the setup without needing the joke explained, built entirely on watching four aliens fail at the simplest parts of being students while their president frantically chases shadows.
Di Qiuren runs the Astronomy Club with genuine passion, convinced that extraterrestrial life exists somewhere in the cosmos. He obsessively drags his club members on stakeouts and investigations, desperately hunting for proof of aliens. The joke is that he's looking in the wrong direction. Every single member of his club is already an alien, all of them working undercover on Earth while pretending to be ordinary high school students. The aliens have a problem though. They need to blend in, which means learning how humans actually behave. They study earthling customs like it's a subject for class, making awkward observations about normal activities and struggling with basic human social interaction. Meanwhile, Qiuren remains completely oblivious, conducting his fruitless alien research right alongside the very beings he's searching for. This creates constant comedy from the collision between Qiuren's genuine enthusiasm for discovering aliens and his club members' desperate attempts to act human while secretly being anything but. School life becomes a series of close calls and ridiculous misunderstandings as the aliens navigate existence in this small corner of Earth.
