My first dorama was prolly Gokusen or Hana Yori Dango as they were aired on local TV, dubbed in our native language, but I never really got into it as Meteor Garden was aired almost at the same time (if I remember right) and that caught my attention more. Though I did love Yankumi. I also saw Zettai Kareshi even before falling into the pit of Doramas and Eigas. I am a completionist, since I saw the anime, I HAD to read the manga and watch the Drama. I was that kind of completionist back then, it had changed a bit now.
Then come 2016, I was roaming around Viki, and there I saw Hero. I was smitten by Takuya Kimura, and the rest they say is History. I found he was a Member of SMAP (it was January 2017 and they have already disbanded that time, T_T Imagine my heart break?) but still I watched a lot of SMAPxSMAP. I saw almost all (around 52) movies and dramas of Takuya, also listened to SMAP songs, watched a few shows of Shingo as he is my Niban in SMAP.
Now I have branched out a bit, I saw a lot more dramas and movies with JA idols as a part of it, but other than that, now I only watch Doramas and Eiga in general and follow other artist aside from idols. Unless I had to, like for Watch Challenge, I never watched from other countries. lol.
I'd probably see Ko's since you mentioned it. Also, it's true that both AniKomma and Kurosaki are something you don't want real life but very much entertaining to watch. I did appreciate AniKomma more than Kurosaki though.
