However, her super-human strength and supernatural agility ends up driving people away from her. Revealing her powers during a play causes people to be frightened of her, and a later incident undermines her chance to talk to the boy whom she has fallen for. Because of this, So-hwi decides to give up studying martial arts in order to start living a completely ordinary life. She no longer wants to take responsibility for her parent's legacy of martial artistry. Soon after, So-hwi succeeds in joining the ice hockey club where her crush Jun-mo plays. She persistently tries to get his attention, and Jun-mo ends up unwillingly taking her with him as he rides his motorcycle after a party. The pair come to a police station, where So-hwi's crush is revealed to goes regularly to see a female police officer. Despite the woman being somewhere around his mother's age and unwilling to return his affection, Jun-mo persistently confesses his love to her. He even follows the officer on her police patrols, tailing her on his motorbike. Despite discovering that her crush already has a one-sided and obsessive love for another woman, So-hwi does not lose hope that Jun-mo may return her feelings.
