With this formulation, it seems that there is an ending in which Kirito doesn't care about Asuna's infidelities, because instead of "current girlfriend" he found someone he can call "future girlfriend"
In another case, it becomes unclear what all this is about. The lustfulness scale is determined by whether Kirito doesn't care about Asuna and whether Kirito likes Suguha? The choices in this game should lead to some kind of logical end, then in the end we get either Kirito, who doesn't care about Asuna, but he's in love with Suguha and loves humiliation(how lucky for Suguha

), or Kirito, who is immensely in love with Asuna and doesn't care about the rest and doesn't know anything about Asuna's infidelities.
