FNC Entertainment’s new boy band Hi-Fi Un!corn (the winning team from the Korean-Japanese survival series “The Idol Band : Boy's Battle”) has released a pair of individual teaser images of Min for their upcoming Korean-Japanese debut digital single "Over the Rainbow" which is scheduled to be released on June 26th.
Alsoo easter egg in the trailer at 2:33 i.e 2nd ep right before kakeru runs to the rooftop, in the class when fujino and kakeru are sitting, the classmate who comes up to them is Shuto from Hi-Fi Un!corn!!!!! Aka one of the guys who sang U&I!!!!!!!! There's also a focus of him live singing the song on yt that i highly highly recommend.
Edit: as an anon pointed it out to me: Shuto is also the one who knocked yamato over in the 1st ep while playing basketball!! Hehe wonder if taemins also gonna show up sometime.
