Debt-for-sex & plunder: The heroine's family business went bankrupt and the family status plummeted. The heroine's father owes a huge foreign debt, and the hero uses this as a bargaining chip to demand "physical repayment" from the heroine.
Marriage first, love later, extreme pull: The male protagonist agrees to marry the female protagonist because of the requirements of the inherited family. The two start with a cold agreement of "not allowed to fall in love with me."
Chasing Wife at the Crematorium: Words hurt the heroine, she is cold, unruly and cynical.
The contrast between the tyrannical and cold-faced male protagonist and the doting one: he is indifferent to others, but he loves the female protagonist unconditionally.
The writing is good (#^.^#)👍🏻
