I wonder how much will depend on the green stripe . As far as I understand it, it determines how much Kirito is lustful towards other women. And what it might mean for the ending. Alternatively, if it is very full, Kirito can agree to Suguha's suggestions. Or Kirito just won't give a damn that Asuna is cheating, since she is no longer the only woman for him.
The ending is where Kirito and Suguha left for America. Asuna calls Kirito. At this time, Inoda fucks Asuna, and Suguha sucks off Kirito . And they communicate, "I miss you very much, blah blah blah, I love you, come soon."
