Secret Angel has the following points in common with Hi! School - Love On :

In both dramas, there is a female angel protecting a guy because of an accident and they eventually get in love. Their love is deep and pure leading to many cute moments. Moreover in these stories there is a jealous female opponent to the naive angel, the ML’s best friend who is secretly in love for him.

HSLO however is a youth romance, they are in high school. This is not the case for Secret Angel.

From the first episode of The Penthouse alone, I can already make parallels. Rich families living in an exclusive property, two students who are competing for one goal, a highly-esteemed teacher, and so on.

They are both xianxia

Both involve love stories spanning over thousands of years.

Both have strong female leads.

Both have male leads that support the female leads with all their best.

Both are historical.

Lastly, both have gods.

Both involve Alzheimer. Beautifully filmed. Gradual progress disease, with family support. Patient in denial, frustration, anger, acceptance. Both are must watch film. Heart warming.

1) Both are xianxia dramas.
2) Both involve heavy use of CGI
3) Both also have fantasy tags
4) Both are historical xianxia romance
5) Both involve gods and demons

Mimi-sensei and Yaeko-san have some resemblance. They also do very similar internal monologues. And their personality is a bit similar although Mimi-sensei is more serious.
But yes, Haru-san always is given this kind of characters in the last time. It suits her very well.

Both drama described the story of strong female lead. And showed how she fight for her dream, the people she want to protect & how she tried to pay the bad guys what they deserve.

And both drama are based on the historical theme with many fighting scenes.

YAMH 2nd pairing's background is pretty similar to SK's main couple.
The romance game in SK isn't as strong as YAMH though since SK is more on personal growth.

The dynamic of the main couple is pretty much the same.
ML saved FL during their younger days.
FL idolized ML but couldn't remember his face.
ML became FL's drill instructor.
Both are about protecting what dear to them (the people & the library)

the iron ladies 2 follows the main character of the first installment a few years after their first victory while also shedding light on their college years as told by jung

I love this trope so much that I can watch countless dramas based on it even when they normally follow similar story structure. Weak student having no dreams whatsoever meets a teacher who help him/her rediscovering themselves and finding success at the end. Cinderella formula can be a little melodramatic compared to Dragonzakura But both have strong motivational story. Well in dragon zakura too, we see many unexpected things happening in last 2 episodes rather than simply following the story and getting result. I loved both of the dramas and have rated them same. So basically they are on same level for me, You give it a try and decide yourself.

>Both makjang series
>Both female lead got pregnant and supposed to get married unfortunately their baby died because of such circumstances
>Both second female lead are in love with the boyfriend of the female lead
>Both male lead betrayed the female lead for the second lead
>Both female lead vows revenge
>Both female lead change their name to hide their true identity

+ ‘Ruthless’ strong female lead character (whose cold exterior hides a lot of vulnerability due to her past).
+ Warm and patient male lead (but who isn’t afraid to call out the FL).

Although with completely different plots, they have similar lead characters and main couple dynamics.

Both movie and drama are written by the same writer and certainly has the same atmosphere. While Fabricated City tells a story about how the main character was falsely convicted of a crime that he didn't do, the plot afterwards was quite similar in which the main character formed a group and tried to punish the real culprit as a vigilante act. The movie also had a great fight choreography and car action as well as SFX and can give you a brief glimpse of what Taxi Driver has in store.

Both movie and drama gave a lot of emphasis on how 'one false conviction is worse than losing 10 or 100 criminals/true convictions'.
