One day, I, Kani Himeki, was dumbfounded by the news displayed on a smartphone screen. The popular idol group "Fallen♡Angel" is disbanding, and the reason given is that one of the members has a boyfriend. "Hey~, were you surprised?" The girl showing me this news with a mischievous smile is Tsuyuzaki Futaba. It's easy to understand why she's showing me this news. Tsuyuzaki Futaba is the center of "Fallen♡Angel," and she is also my girlfriend.
