Wu Lian, a student just starting his final year of high school, gets bound to a System that actually forces him to wear a bunny-girl outfit and do square dancing in front of the entire school.
No dog would take this... task. Fine, I'll take the System's mission.
It's just dancing in a bunny-girl outfit. An SSS-rank ability in exchange? Worth it.
What? He has to wear leather and gyrate on the street? For the reward, he'll take it.
What? He has to pin someone against the wall, pretend to be deeply in love, and deliver cheesy pickup lines? For the reward, he'll take it.
What? He has to publicly admit he dares to eat poop? And demonstrate it in the cafeteria when it's at its busiest?
Th-this...
From then on, the System leads Wu Lian down a path where the more absurd he gets, the stronger he becomes.
