There is more but this is main
I am sure you will like both.

Both have one of the main leads as a supernatural character..
In OM the female is a vampire and in MAB the male lead is an immortal..
If u liked orange marmalade then you will most definitely love my amazing boyfriend.
The only main difference to keep in mind is that OM is a kdrama and MAB is a cdrama.

This is an old drama that came to my mind.
In the cdrama they switch emotion and pain between each other.
While in the kdrama they end up switching souls.
It's kinda similar n kinda not soo

Both the dramas have a similar situation....
In both the dramas the main leads have a contract marriage.
They get to know each other because of the misunderstanding of the house.
Even though these two things are the same the rest is very different.
Like the way they fall in love
Their relationship progress
Their profession...... Etc
From me Midsummer is better than P&C but if u are looking for a contract marriage vide this is a good drama to watch.

I really love this drama.
It has a great school setting.
It has one of the best bromance.
I love the main leads.... Both of them.
The romance is pretty good.
All the teachers are good except one evil teacher.
The ML also misunderstood at the start of the series
The personality of ML in both the dramas is kinda the same - cold, cool & closed off from the outside but sweet and warm on the inside.
This is one of my favourite dramas n highly recommended.

The biggest similarity is that both the dramas take place in a high school environment.
The main leads have a cute romance going on.
There is also the fact that the whole class is like a big group of friends with the obvious foe turns to friend situation.
Anyway this is a really good show too.

In the drama Hwarang one can find martial arts as a common point.
Also both the dramas focus on teaching morals that help an individual grow in life.
Both the dramas also have a school kind of setting.
The bromance in both the dramas is strong at the end of the day.
The biggest difference between both is that Hwarang is set as a historical drama.
I highly recommend Hwarang.. It has a little bit of comedy and it is fun to watch.

In both the dramas the story takes place in a school environment.
Both the dramas contain the supernatural element of the story.
Both the dramas also focus on the friendship aspect of the students in school.
According to me both the dramas are a must watch... They are really good.

Both the series have a school based theme......
Both have a love hate kind of situation
Both the dramas have that one teacher who is connected with a student....
The best thing is that both of them have cute scenes and have a happy ending....
