So I am just curious but why is the name "19days" Any ideas ??

even i have the same doubt

If i remember it correctly , they plan on making a band named "19 days" hahaha not sure

I only know like it's captioned on the top of every chapter, "one day" will be their future band name, at least that's what decided for now. But about 19days I'm as confused as u r. Maybe they will again come back together as a group when they are 19? Currently they are 15-16. Maybe they will change band name? ╮(￣▽￣)╭
