@phoebusg eh, i defintely get the other way around. Not always, but an excellent book with a well-crafted world (i usually read scifi/fantasy, where that would make sense, but even non-fiction has it’s own ‘world’ seperate from ours) I tend to get sucked in, and really enjoy my time there. To finish the book means to end my time in that world. Even rereading isn’t quite the same unless there’s been years in between for me to forget (not that I don’t, but it’s not the same).
So, to @senthilkumar, I think it means that. They’re having a great time with you, and they never want to go back to what it was like before. It could be love or infatuation, really. They so often feel the same. But it is quite romantic.
