I've been looking for this anime! I keep seeing pictures without captions sometimes and i kinda gave up...but woo! now i can watch it! (i meant the one in the pic btw
...I always have this sort of headcannon that HTT helps/would help 뮤즈 with their 음악 and that Sawako-sensei sometimes helps with the costume designs and 음악 Video settings. (Since she seemed to have made a fairly good recruitment video that one episode in K-on!) That would be pretty good to see...maybe i'll make a fanfic about it,who knows? xD
