this is so funny and have a fast update
the old man seems so young, he have a baby face, and he helped the female lead (a scholar) in every trouble she have
the plot is about teacher-student relationship, they are married for the girl's sake in order to protect her and her brother
the male lead "buy" her in order to save the girl's life and then they live together and the girl helped his job
it's have an interesting plot story
looks like they made an "idiotic-funny" couple after being married
the little girl is having a crush with a guy who much older than her
it's unusual love story, because the princess has falling in love with a king without head, also her love for him is pure. overall it's interesting.
