Before starting university, freshman Cheng Huan is told by her father that her military training instructor is the son of one of his old army buddies and will take extra care of her. Trusting him, she brings drinks to introduce herself, only to be hilariously punished with ten laps for allegedly bribing the instructor. At her law-focused university, all the military instructors are senior students from the police academy, so she had expected special treatment but ends up in an embarrassing misunderstanding instead. Meanwhile, back at the dormitory, she discovers that her bed has been occupied by He Jinna, a roommate with powerful family connections. Between amusing campus adventures and unexpected little troubles, her university life gets off to a chaotic start.
