[Woman Disguised as a Man + Reborn Male Lead + Rivals Turned True Love, A Delicious Romance
Childhood friends against childhood friends, both chaste, angsty and coercive]
A mighty female God of War vs. a lovesick, doting husband
Everyone in the capital knew the Prince Regent absolutely despised the Duke Who Guards the Nation. Their feud had begun when they were young, and they'd once been so at odds they couldn't stand to be in the same room.

Prince Regent: ...
Duke Who Guards the Nation: I want to be a good man, loyal to the emperor and devoted to my country. But lately, the emperor has been wanting to sleep with me, and it's giving me a headache.
Content warning: The leads aren't saints. They show no mercy to political enemies or personal foes, and will wipe out entire families without sparing even close relatives. They're both fiercely protective and hold double standards. The male lead clings to her and forces his way into her life while being a “hot face washing underwear.”
