Kim Taeyeon, aka "Human Paper", decided to sign herself up for a gym membership after being teased by her colleagues for being weak. Her confidence continued to dwindle down as members of the gym make fun of her for not knowing how to use the machines available. Luckily, she was saved by the hottest trainer in the gym under the name Jung Jessica. From then on, Taeyeon became stronger, more confident, and... obsessed

There is a new girl in town and it turns out, she becomes Taeyeon's neighbor. Jessica Jung is her name and she is coming from the United States of America. Taeyeon's world is rocked and her mind is boggled upon meeting such a seemingly cool girl. What does one do when there is an overly attractive person living right next door?
