I'm guessing it's a bit late to be posting this, but I just started thinking that the name "Lina" might be a bit wrong. Based on the reading it would be "Riina," which in finnish is a more common name than either "Lina" or "Liina" combined, though they are also valid finnish names.
At this point it's probably too much of a hassle to change the name in all of the notes, and also we don't know the exact intention of the author. Just thought it might be worth mentioning.
