Knight of the Rose (2022)

A strong female lead. Two main characters who are opposite ends of the spectrum...a cold/withdrawn ceo and a talkative, strong minded woman soldier.

Both male leads are CEO'S with bossy characters, strong bodyguard female lead,overprotective father of the male lead, happy ending.

Both dramas story plot evolved in finding a cure for cancer.

Almost have the same finale presentation where there's a bomb explosion and survival training done by the MC that was applied towards the end.

Both male leads are wealthy CEOs and both female leads are hired as the male lead's body guard.
Strong Female Lead Bodyguard + Arrogant Male Lead = Similar Plot.
