The story of two tsundere leading a scheming villain, a brainless miracle doctor, and an unhappy hero to solve a case.
Absolutely HE.
The male protagonist is a scoundrel, has no image, is not elegant at all, and is not a handsome young man.
The heroine travels back in time, an older woman, who knows no martial arts, is neither elegant nor courageous.
Grudges and strange cases are indispensable, but they are not necessarily violent and bloody, and they will never delay romance_(:з∠)_
