The Lion's Secret (2021)

I think it’s similar with the kidnappings and a mysterious enemy. Also the military aspect somewhat.

Cold Woman/ Warm Man
ML protecting FL
Somewhat pretend relationship element
Business Genre
Chemistry between leads

story follows the bodyguard and vip relationship , one have responsible ceo and other have irresponsible they both have life threat which comes to need a bodyguard . slowly both couple develop understanding and fall in love . now its not only a duty they try to save their loved one ,

both have bodyguard and vip relationship . both female lead is the heir of extreme power one is company ceo other is crown princess whom family/profession life is messed in power struggle and life are in threat. both female lead are strong and draw the line between people and her to safeguard herself . both male lead are defense personnel one is ex military officer and other is Lt. commander position . both male lead was approached by female lead's father to protect his daughter and their comes marriage of convenience .

Both dramas seems to have ML and FL who marry each other for their own circumstances. Both have love developing after marriage and both do no know each other really before they marry. Marriage starts after love and ex boyfriends show up.

Similar background but I didn't draw the similarities at first
- FL is born with a silver spoon (*but* FL in TLS is currently running the company well)
- ML has a first responder background (good physical ability) and is wise and is appointed by the FL's father/grandfather to take care of FL
- People try to sabotage FL's control of the company
- FL experiences growth in management ability/responsibility
- family secrets/international excursions (there's more in TLS)
- of course, the classic exaggeration of romcoms but it's a fun ride
Of course there are differences...major one might be that SMH is lighter than TLS

they have an almost identical premise.
~contract marriage.
~childhood friend.
~female CEO.
~companys internal conflict and much more.

Military guy coming into the business world after retirement. The FL and ML help each other to achieve their purpose.

Similar cause both are married and then fall in love slowly.
Different cause one is about revenge and other is where the husband wants to protect her

Both have marriage first then fall in love but one is about office romance and other is university.
