Are they still in London because Lyle could just go back to NYC for that LDR experience if he really wanted it
They live in London, for Lyle he usually have business trips in other countries and can possibly spending moths there (I remember he once mentioned in the novel that he would have had stayed in Canada for half a year but he turned that down because he wants to stay with Ash). For Ash I think he lives most of his time in London
BUT I DON’T EVEN CARE BECAUSE THE CHARACTER DEVELOPMENT IS SO GOOD. I’m gonna assume that it was a time issue that it couldn’t be included. There’s always next time ╮( ̄▽ ̄)╭
