I followed J-Pop when Ayumi Hamasaki started and K-Pop (my friend introduced me to SES and BoA) when I was in high school 1 and a half decades ago. Stopped listening to K-Pop after SES disbanded.
I played DJ Max portable for the PSP, eventually they added KARA songs to the PS VITA game (Technika i think, end of 2012 I think) and I was hooked. I didn't follow them much because that was around the time my little brother passed away so I didn't really update my music at all nor look at any news (I only grabbed their first 2 japanese albums). My mp3 player's file systems finally got corrupted this year and I didn't back up most of my music so I'm slowly and lazily reorganizing/converting everything again. As I was doing that I started trying to find concerts to watch on the side as well, remember hearing about SNSD so I downloaded their Tokyo Dome concert. Then I was looking at the list of girl groups that went to Tokyo Dome and found out KARA went before them and I was like oh yeah, KARA!!! Rediscovered KARA through the KARASIA concerts in Japan and I was hooked again, they're definitely my favorite group. LOVED their tokyo dome concert. Bought all the physical copies for their concerts on blu-ray and went through it + music videos with my friends, still waiting on their 2012 korean one with eng subs from yesasia and I'll finish watching all of them. Loved their japanese albums too, but I need to go backwards and listen to their korean ones.
I need to watch their shows too if I can find them, just finished watching the Hara On & Off one.
