i visit korea every year! i just try to plan my trips in a way they align with concerts or cb season. but even if i didn't get a ticket i wouldn't be too sad since seoul feels like home to me :) and it's not like i only fly for the concert(s)! i think if i were to only fly for a very short period of time i wouldn't risk it like that, although for tws maybe i would. but again i love korea anyways so i wouldn't be too upset. but to answer shortly yes i usually don't fly just for a concert, but i try to plan my trips in a way where i could fit the concert in the timeframe that i will be there! and i don't really have a reason, korea just feels like home to me so i really like going back <3
