@Riot Lore Persons - Does Rakan not actually love Xayah?

I was listening to the VO today, and I noticed that when Rakan asks Xayah what she would do if her were gone/dead, her responses are "I would be empty without you" and "I would burn down the world" (some paraphrasing). However, in Rakan's VO, there is a couple lines that sound like lines for when Xayah dies that are "Hello world, look who's single!" and "I miss her already... Oh well!" Plus, a lot of his VO lines are very self-centered "what do you think of my beauty and awesomeness" kind of lines.

So, my question is does Rakan only care for Xayah because she is just a fan who adores his beauty as much as he adores his own beauty, or does he actually love her?

Not sure if this is a question that cannot be answered at this moment in development, but I am curious to know more about them as characters.
