Namida mo Tooku - Aonibi no Nemuri (Spin-Off)
I wish silver butterfly had been longer there is so much potential for it to be another 5 or 6 chapters at least with stories dedicated to tounen and harasaki, Yagarasu and Fuji as well as the brother and souichi (back ground wise) a sequel featuring all their loves set 5 to 10 years later would be good too
there is a spinoff Namida mo Tooku - Aonibi no Nemuri
