This blog is dedicated to posting Who's Whos for Kpop idol groups' MVs. What's a Who's Who? It's a post in which I include at least one screencap of every member of a particular Kpop idol group, from a particular music video, accompanied by their name. If you have a request for any MV (Kpop idol groups or otherwise specified Jpop groups only, please), I'd be more than happy to create one for you. You can find all the Who's Whos entries under the tag Who's Who on the left hand sidebar. You can also search by group tag.
In addition to Who's Whos, I also post occasional 101 entries that keep track of lineup changes, bloodtypes, birthdays, who this year's rookies are, etc. These can be found using the 101 tag on the left hand sidebar.
