They are completely different stories, but the feels of both the female leads (FLs) are the same, that they both sing in a band and have great voices.

They both perform in front of a big crowd, that is why I got the same feels. The songs on both of the movies are great too.

The leading men are also both handsome and has a lot of charm. If you like movies with music on it, watch both movies.

It is similar in a sense that it is a marriage between a minor girl (a high school girl) and an adult guy.
In MLB, they got married because of a grandfather's wish. In PJK, they got married because the husband is conscious that people will say something if he pursues only a relationship with a minor, so he chooses to marry to make things official and protect the girl by making her his wife.

They are similar in a sense that in both movies, the "marriage" had to be kept a secret from school and classmates. Only family and some close friends know of the "marriage". Both families have approved of the said marriage.

Only difference is on MLB, the girl purposely had a relationship with another boy just because she cannot accept the marriage as it is. But on PJK, the girl cannot accept the fact that her husband is a policeman and is always in danger.

Both are cute and are just on the getting to know you stage since it involves high school girls.

From the sypnosis, sounds like The Secret Life of My Secretary is similar to What's Wrong with Secretary Kim.

Both have bosses that fall in love with their secretaries. Both have secretaries that is a long time trusted worker for the boss and they are the only ones who knows what the boss likes.

Clover and GoHo's Starry Night are similar in the sense that both successful female leads are pursued and then fall in love with their hostile and tyrant bosses.

They are also same in the sense that both bosses have a hidden feeling for the female lead. Also, both female leads have an old flame or ex love that turns up again and makes the current male lead (the tyrannical hostile boss) jealous.

Also, both hostile tyrannical bosses secretly covers up for the blunders or mistakes of the female leads, without the female lead knowing, just because the bosses likes or loves them in secret. Both bosses are just hostile and cold on the outside, but has a soft and sweet side to them.

Il Mare was remade into an American Movie "The Lakehouse" and that is what I watched. Then I also watched Teacher's Diary. I felt similarities in both stories because it both tackles communications between a male and a female through written documents (in Il Mare, letters, in Teacher's Diary, the diary). There is also a longing for both couples in both stories. The only difference is that in Il Mare, it is kind of like a time travel element or something crossing between years. But in Teacher's Diary, its more of like, just alternating each other in the teacher's post, but it is in real time. In both movies, the male and the female leads meet in the end, thank god. But seriously, they have both the same feels when you watch them.

Both are about English teachers or translators "helping" translate something to the partners of their clients and then eventually falling for their client. Something like that. They also focus on the English language. Both are cute and entertaining.

Both dramas have a female lead that comes from a poor family that poses as a rich girl as a swap because the real rich girl died and the one of the male leads had to do this to save his ass.
The difference would be that the poor girl that had to swap for the rich girl in King Flower, had to get an operation to look like the rich girl. But on Mask, the poor girl is really the doppelganger of the rich girl.
Another difference would be that, the guy who made the swap in Mask, is the brother in law, not the husband. In King Flower, it was the husband who made the swap for his wife and the poor girl (with plastic surgery involved).
But in both dramas, the females both had to live with a pretend husband and their struggles begin. But eventually, both couples from these dramas fall for their pretend husbands.

Both deals with a man and a woman having a one night stand, but the man is serious about the woman and then gets separated. Then they somehow meet each other again and end up together. Like, one night stands are kinda scary for females but if the men are serious to have a relationship, it would make all the difference on the risks.

They have both the "Bestfriends turned lovers" theme... Like, you are already secretly in love with your bestfriend, but you guys are still denying it, keeping it, or don't wanna ruin the friendship...something along those lines...

They have both the "Bestfriends turned lovers" theme...
