Lin Sangyu is a sugar glider on the verge of starving to death when she accidentally glides into a rather unusual villa and discovers something incredible inside: her favorite bugs. Lin Sangyu: o.O How is this any different from a mouse falling into a barrel of rice? It takes Lin Sangyu exactly 0.01 seconds to decide she's secretly moving in. The villa's owner appears to be a mysterious man. He leaves during the day, returns at night, and follows a routine so strict it's almost rigid. Then he discovers her. Without the slightest mercy, he grabs her by the scruff of the neck and tosses her straight out the window. Lin Sangyu, internally: My meal ticket, you think you can escape me? Determined to keep freeloading off him, Lin Sangyu pulls out every trick she has. Every time the man throws her out, she finds another corner of the villa to sneak back in through, squeaking indignantly as she flaps her pitiful little gliding membranes to make her displeasure abundantly clear. Through sheer shameless persistence, Lin Sangyu finally earns herself the blissful life of having her every need catered to. When she's hungry, she clings to the man's wrist, rolling around in his palm and acting cute until he feeds her. When she's sleepy, she curls up in the crook of his neck, or waits until he isn't looking before gliding onto his two-meter-wide bed and snoozing away. When she's bored, she climbs his tie onto his shoulder and stares at his documents with huge, round eyes. She thinks her days will remain this carefree forever. Until one day, she transforms into human form—and the man catches her by accident. Tears well in Lin Sangyu's beautiful eyes. Clutching the hem of her clothes, she looks at him in panic.
