Oh, sorry, I should have combined this with your previous ask, I wasn’t sure at first which closeted anon you were but the longer ask I just answered, I’m assuming.
And yes, Clea pointed that out too, that they got engaged quite a while later and there is the assumption Harper and the couple’s issues aren’t all cleared up immediately. But I kind of wish they’d saved the proposal for the sequel, heh, although of course it was a sweet epilogue.
