Both of them have very good looking main leads. The female lead initially set up a marriage just to take advantage of the male lead for revenge and the male lead knew about it, but after living together the seeds of love begin to grow between them. The male lead is always there and help the female lead. The male lead fell in love first and always confessed his love but the female lead never confessed her feeling, even though over time she actually fell in love and really loved the male lead.
