(A = first choice & B = second choice)
Kaoruko - BAAAABAB (Wedding END 七々原 薫子)
Keiry - BAAAABB (Accounting/Business END ケイリ・グランセリウス)
Kaori - ABBBAABB (Kaori END 神近 香織理)
Utano - ABABBBAAB (Gozen END 哘 雅楽乃)
Awayuki - ABAABAABAA (Reisei END 冷泉 淡雪)
Fumi - BABABBBB (Watarai History END 渡會 史)
Also the reason why I use A & B for choices is because the game isn't translated (meaning it's all in japanese pretty much, even the interface & menu)
the japanese walkthrough can be found here.
