Looking for a drama

So I’m looking for a drama and I don’t remember if the drama is Thai or something else. The Main girl is an illegitimate daughter who sees spirits or ghosts and her step sister is supposed to marry a prince but everyone’s scared of him so they send her instead since they don’t like her . I also remember a scene where her and the prince go to his sisters birthday celebration and she doesn’t have a present so a flower fairy or ghost helps her make a flower crown out of some rare flowers. At that same celebration the prince and her make a covering out of some cloth because it starts raining. I remember all that but not the name .-.

omg thank you!!

So they do have a real life version  but unfortunately it’s not that one. Thank you though!!
