Aida and Ophelia have one big arc with 6 possible endings.
Scarlet has 4 arcs and 4 possible endings. The first 3 consist of just one choice and are mostly political. The last one contains 2 choices, with the first one determining the second. It alone determines which of the 4 endings you get.
Camilla, Chatherine and Lohannah have 3 arcs and two possible endings. Every choice influences a scale that determines the ending. The first arc contains two choices and the second choice changes depending on the first one again. The second arc is just one choice. The last one is the same as the first, but each choice counts double, except for Chatherine.
