Joo-ri and Yoon-ah, both second-year students at the same school, meet on the rooftop. The two have recently discovered something that happened between Joo-ri's father, Dae-won, and Yoon-ah's mother, Mi-hee. Wanting to prevent the situation from escalating, Joo-ri tries to handle it somehow without her mother, Young-joo, finding out. But Yoon-ah, saying she has no interest in the adults' affairs, wants nothing to do with it. Just then, Yoon-ah picks up Joo-ri's dropped phone and answers a call from Young-joo, and ends up revealing a shocking secret that had been hidden all along. Seeing this, Joo-ri is thrown into total panic.
