왜냐하면
애슐리가 좋아해주니까요!
Could anyone tell me what that means ? Does it have something to do with liking something or someone?
왜냐하면 is "because", abbreviated from 왜냐고 하면, which can be directly translated as "if you're asking, because ...".
The easy explanation " because, 에슐리 is liking something" or
" because, 에슐리 is ( what someone like) 좋아해주니까요"
As a result something or someone
They are both possible.
It can be translated into 'since Ashley like it.'
And yes it has to do with liking something but what Ashley likes isn't mentioned.
