An idol-duo.

Now third-years, they formed an idol group as first years with 3 third-years and 1 second-year. After the third-years graduated, the 3 of them didn't really manage to find new members, and after the 1 then third-year graduated as well, the two of them were the only ones left, and decided to keep it up for the sake of their senpais, but they aren't really looking for new members anymore and are comfortable with having made the memory and leaving it at that.

While friends, they aren't SUPER-close, but they've had a little success with the route of pretending to be all intimate and close, singing lots of Garasu no Hanazono-type songs. The blue-haired one has a boyfriend, something she keeps secret from the public because of the whole big deal relationships are for idols, and the blonde agreed to to help her out keeping it secret with the pretense.

By the way I most likely won't do anything with them, just had to get the concept out of my system.
