Kim Y/n, a nineteen years old shy girl who badly wants to pursue her dreams to become a journalist but her best friend Yuna persuaded her to audition with her. Luckily both of them got accepted, then Y/n joined the survival called Sixteen. She didn't expect that she can join and will became a member and maknae of the girl group called Twice. Her unnies treat her with so much care like she's their little sister. Chaeyoung keeps avoiding Y/n, because her feelings grew deeper and deeper and afraid to not be loved back, but what Chaeyoung doesn't know is that the younger one also likes her. The clueless maknae don't know what's the reason why her unnie is acting like that. Y/n confront her and ask what is wrong. Until one-day Y/n couldn't stand Chaeyoung's cold treatment anymore so she ignored her unnie.
