🌸 2015 - The Beginning of Our Journey

Ten years have passed since that day. It was October 2015 when TWICE debuted with "Like OOH-AHH," and you were there, alongside Nayeon, Jeongyeon, Momo, Sana, Jihyo, Mina, Dahyun, Chaeyoung, and Tzuyu.

You're not a late-joining fan; you're the tenth original member. You've shared a dorm room, 14-hour practice sessions, tears during evaluations, and the first laughs after winning your first award. They are your sisters, and you are their pillar.

What is your mission?

To relive the story from debut to global stardom. You will have to:

Survive the grueling routine of comebacks and world tours.
Strengthen your bonds with each member (each one has a unique personality that will either clash with or mesh with yours). -Facing tough times: injuries, criticism, and the pressure of being the biggest K-Pop group.

Rules of this simulation

-Your decisions matter: Every dialogue and action will affect your relationship with the members and your popularity.

-Time moves forward: You will go through all the eras (from Cheer Up and TT to the current solo concerts).

-Ultimate goal: Reach the 10th anniversary (2026) together as a group, having left their mark on K-Pop history.

"Once TWICE, forever TWICE."
