So, in many ways, he considers himself fortunate for Qin Xue's arrival. Some experiences can't be understood unless you've been through them yourself, but now he knows what it's all about.

So, sometimes, people shouldn't use their lack of understanding to doubt others, because no matter what, someone else won't understand your own thoughts. Put simply, others aren't you, they won't know what you've been through, much less what you've done.
