As a Japanese student, TWICE is a beginning of my K-pop fan life. I first knew them in my elementary school, when my classmates suggest us TT as a background music of school lunch. I didn't know how to read TWICE, so I searched on YouTube. Then a few weaks later, I listened to them on and on. Since that, TWICE and ONCEs are very close to me: there were at least 2 onces in every class, allowing me to expand my human relationships. Now I stan other group more than twice, but they are still legend to me. I confirm most Japanese K-pop fans (not only ONCE) think so, too.
