blabla100:
From my pov, he said that the person XY likes is not him as to make a point out of how he never allowed XY to like him or reveal his feelings to her, so he should not worry about that.
So I just watch eps 1 so I don't know which part in the drama this dialogue of XL was added. However there is some hints for his word:
In eps 1 inside the casino, XL asked XY who she liked. And she said the only she liked was the one she wanted to spend her live with.
And there is a footage about their conversation outside the casino (maybe in eps 2) when he left. Someone asked XY who that was. And XY said he was someone who eventually could not accompany her.
From these 2 hints, may XL lead to such conclusion?
