Well, I'm not very good at English, so maybe I misunderstood some of the sentences the game is saying.

There's one sentence Mary said, I'm not sure if I got it right.

Please see the picture below.

The sentence under the red line that I drew.

What I understand from this sentence is that it seems Mary had experienced it before.

But as I look at the story that the game describes until now, I think Mary has never had a lover before, but why does this sentence say like Mary has experienced it before or am I misunderstood?

As you know, Mary didn't give pendant to anyone.

So how is it all going? I don't understand, or is it because I misunderstood the language?
