Obsession

解锁12d的条件是解锁11b
解锁11b的条件是解锁6b 然后从6b打到11b
11b一开始点桌上文件选：
C: “Memory is what you are, whether it’s real or not.”
B: “There were so many of you, what could they do to manage that hell when there were so few of them?”
B: “To a certain extent they were trying to make you feel better. You were lost souls.”
A: “You were too many and they were too few, it was impossible to do otherwise.”
C: “Perhaps Renée really did know! You can’t be sure of it, you know that, don’t you?”
A: “Human misery was thrown in here and locked away to make the world forget about it.”
然后到包裹寄放处找到一个包裹 窗前打开 然后听到音乐 去到护士房拿到音乐盒 接下来一路走到户外一处房屋触发动画（具体不知如何描述 我看的是视频攻略） 动画过后解锁

12-d太带感了请务必走这条线进13章
