突然之间，有一个男人闯入她波澜不惊的生活，她一直试图适应这种突然的改变。他送她鲜花、巧克力、诗集，带她去正宗法式餐 厅吃饭。他是细心而行动果断的人。发现她只穿白色的衣服，便送她白色的真丝连衣裙，一眼就可以看出价格不菲，因为每一个细 节都细致无缺，捧在手里会像是流动的月光。奢侈并非金光闪烁的富丽堂皇，而是在细微之处亦精致完满。
他对她很好，她都明白，只是她不知道该如何表达对他的情感。这是她从来不曾学会过的事。他只是不够耐心，也不够了解，一厢 情愿地以为她是他认为的女人，直到后来发现不是。 他在她身上花的心思，只是长久试验的结果。看似独一无二，其实是批量复制。是先前那些女子留给他的经验，不过对于一片空白 的长安而言，已经足够。 只是婚姻并不像约会，永远花团锦簇花好月圆。誓言刚说出口，便已经冷却，消失在空气里。 彼此不够了解，不够爱，不能够互相妥协，所以不能长久。
