爱情来了，谁也挡不住。

Very easy to understand,
When loves come, it is very hard to resist.

Theres a boy,
who says he only 谈琴不谈情。
at the end, he love a girl,
without knowing it himself.

Obviously,this boy is taken from a movie.

When one is in love,
the person can do anything for him/her.
Even if that boy has a will that stops him from loving one,
he could not resist it.
Because,
爱情来了，谁也挡不住。
