Ok, if anyone else had trouble telling people apart with the constant camera shifts and amount of people and intimacy levels in one room, here's a chapter breakdown that helped me:
Yori Asanagi. Short dark hair. Main character. Current girlfriend of Kino.
Kino Himari. Small girl with short orange hair. Main character. Current girlfriend of Yori.
