the early start seems good enough... until the uncle suddenly come and beg her to get marry without any reason, and she aggree just because... fortunately there is political reason beneath, that is quite make sense...
and it seems there will be something like curse or magic laying behind, so not entirely just a normal romance kingdom story either... prince seems like have a hidden power too, maybe he is an exorcist or something?
looks like it have potential, will follow it for now...
