This will really hit you hard. If you've been following Twice for a long time now, or if you at least know what they've accomplished over the years, this can be very emotional. Seeing how they all started with just small dreams of debuting and winning 1st place in a music show, makes you look back on how Twice really started from the bottom and rose to stardom becoming the most successful Korean girl group thus far. They always stayed through to themselves and stayed humble, that's why a big number of people love them for who they are and stuck with them through all their hardships. This is definitely a must-watch for Twice stans, Onces.
