how 能引导定语从句修饰名词吗?

这个关于他们如何认识、相爱以及结合的故事是历史上最有名的爱情故事之一.
主语是the story,how引导的句子是说明story的
这里how引导的是名词性从句,在介词后相当于名词
另外,how引导名词性从句有如下几种情况：
1.表方式、方法,相当于the way in which.可译作“怎样、怎么”.例如：
I didnt know how he came here.
2.表程度上的感叹,可译作“多么……、真……、这么……”等.例如：
He said how beautiful those flowers were.
He said how he regretted the hours wasted in the woods and fields.
He was surprised at how much water I had drunk.
3.表对程度、数量、情况的疑问.例如：
She wondered how he loved her.
I dont know how many students there are in our school.
I have no idea how my mother is now.
I want to know how he is getting on with his studies.
4.仅用作连词引导间接陈述句,本身无意义.例如：
He told me how (= that) he had read about it in the newspaper.
5.用作连词,相当于the fact / situation / times...that,可译作“……的样子”、“……的情形”、“……的情景” 、“……的经历”等.例如：
I still remember how they laughed.
I still remember how I left my hometown for the first time.
I wont forget how we lived together.
I wont forget how I lived in my childhood.

how引导的句子是说明story的,主语是the story

OF在这里是从属关系,修饰the story表示是怎么样的一个故事.这里HOW不是定语从句.

of 后面是宾语从句，how不可以引导定语从句，因为定语从句的前提是有一个先行词可以用来修饰作定语，how没有可以对应的先行词。

唉！
这个是宾语从句，how 引导的句子做of的宾语。
定语从句是没有why how
