Love the second leads in both of these dramas. It is for different reasons but both of the leading ladies have a ruddy unattractive appearance. Both dramas follow the usual Rom/Com formula (leading man is successful and handsome/leading lady is hardworking and has a good heart). In both dramas the leading man is drawn to the leading lady due to his own insecurities/fears.

Love the friendships in these! Both are about supporting your friends as much as they are romantic comedies. In both of these dramas, the leads knew each other as children.

Both movies are based from true events. Both are about patriotism and perseverance. :)

What they have in common :
Both are Romantic Comedies. Hwang Jung Eum is the leading lady in both. In both, leads met as children and meet again as adults, although there is more of a connection as children between the leads in SWP. Both follow the typical Rom/Com formula (beautiful but unfriendly male lead/ hard working female lead). Both have wonderful second leads.

King2Hearts was 100% better. If you want the training, the growth of a playboy into someone formidable, who never looses the romance and fun in life, K2H is for you. The female in K2H is also 100% better than the character in 7th Grade. To me, 7th grade tried to pull a K2H and failed badly.

Both dramas have Eun Ji as the female lead and in high school setting. Romance involved.

In both dramas, the mother abandoned the daughter and remarried to a wealthy family after that.

In both dramas one of the partners loses his/her memory and can't remember the person they were married to or why they did marry them.

Both drama depicts inspiring stories of school life..
About love, conflicts, friendship, betrayal, character development and fulfilling of dreams...
About learning from one's mistake and making it right...
Both also has a love triangle with really good chemistry...^_^

In both there is a suspicious cast of characters a whole lot of dark secrets and at least one dead body.

mind and psychological games on TV show, with some twists and mysteries here and there

Both sexes were two with the difference that in the story of a man on high heels lady dady person can not change his sex, but the story of the impact of the face's gender reassignment,...

Even though the plot lines are different, the protagonists are mothers whose relationships with their children get better and closer as the shows advance. Angry mom is a lot darker show.

Same main plot idea about a King and Poor commoner switching places

I like to compare both main characters and their self absorbed point of view in life. Both films are a book adaptations which depicts depression, suicide, sex, loss and life. It may be a bit slow but the story line, cinematography and acting makes up for it.

All together, both movies are beautifully written, definitely not a waste of time to watch.
