I'm not sure if anyone asked this before, but is this Kan guy supposed to be Korean? I'm Korean myself (a very shitty Korean at that but still Korean), and that definitely sounds like a Korean last name... although it seems that's actually his first name and his mom just gave him that name to make him "unique," so I guess that probably explains that. Still, he definitely looks like a depressed K-pop singer or something along those lines, and I'm glad that Ranka (I'm assuming that's Rankarana?) vindicated my opinion by calling him Bts-kun.
Anyway, I'm definitely enjoying the story a lot. As others have said before, it's amazing to read a long yuri story that actually starts with the main characters hooking up, and I'm invested in the characters too... well, the two main characters anyway, I'm having trouble distinguishing between the two bands since I thought that Miwa was in Saeko's band? Well, I'm sure something happened that I just forgot about haha.
