Every year around this time, South Korea's 18 years olds (and older for those who did not pass the first time) take the Natoinal College Entrance Test, or whatever the official name might be.
I will count whose support messages had the most views. This year, I have looked for any messages from BTS members but could not find any.
Only people relevant for KPop are counted.
Kim Yooyeon(TripleS) - 396K views. She is enrolled under Ewha Women's University, considered to be the most prestigious woman's university in Korea, making her one of the better educated idols in Korea.

I stop here. SM acts are well known for never doing such support videos, and the NCT video is a copy from its instagram.
Among the 18 years olds , other than Kim Yooyeon who actually had taken the test a few times (she attended a university before quitting and trying again), the most popular were Davichi, Alpha Drive One and IU.
Davichi and IU are old enough to be called their mothers, so I wonder why they still follow such figures instead of people more similar in their age range.
