same plot story about two women friendship broken, because they fall in love with same person

The unpopular girl at school grabs the attention of the popular boy at school.
Though different plots, its a similar look at how one is seem inferior in the relationship.

This also tells story about love between teacher and student. Though they know it's forbidden but finally happy ever after was found when the student graduated from high school. It's a beautiful story about fighting for love. Love it!

Both dramas are related to the past and the present and both sisters in the drama fought for a man. Both have super natural scenes.

same school settings
beautiful bromance
amazing love story without the usual misunderstandings

Drama is about time travel and medicine. I think that Faith and Live up to your name are matched very well. Both good and fun to watch.

almost similair story Seo Jin Woo has the condition of hyperthymesia, which allows him to remember almost every day in perfect detail. To prove the innocence of his father, Jin Woo becomes a lawyer. He struggles to prove his father's innocence, but he begins to lose his memory due to Alzheimer’s.

-For some circumstances both female leads want to spend a night with the male lead.

-Both have a superstitious element.

9/1 is a continuation from 9
Characters from 9 are now adults with children
Exactly the same themes of family, love, conflict

- It looks like a detective drama, but it's actually more psychology crime
- Have Haru on both

- Maki Yoko as a lead
- Women struggle on a men-dominated world
- Gay/bisexual character
- I adore Eri-Miyaji as much as Airi-Chika-Nitta
- Girl power
- Catchy soundtrack

And the opposite is true too.
Plus add with them Sassy go go / Cheer up
and Who are you? School 2015.
as the four of them revolve around a high school romance comedy drama with some love triangles maybe although it wasn't really a love triangle in school 2017.
But it is just that hi school love on has some supernature genre which is extra but it's still amazing.
and also the four of them has the concept of bulling in them which make the drama more intense.
These 4 dramas would be your favorites if you like the high school - youth - romance - comedy type of dramas,like really i adoreee them!
School 2013 is great too but there is no romance in it so i didn't mention it but it shows what hardships friends might face and so on so if romance is not the main genre that you're looking for, you may check out this one too as the bromance in it between Lee Jong Suk and Kim Woo Bin is so cutee.

Both dramas have law and politics as main plot. Defendant is more drama because the case itself involved the prosecutor life; in Stranger, the prosecutor's family is not involved on the case, his life is not the main plot.
Both have a reliable and strong female lead. In Defendant is the lawyer and in Stranger is the Lieutenant.

Basically a remake but in Thai !

All the characters are interesting ! love the triangle in PH Thai

Both contain a similar plot : one girl who became princess within a couple of weeks !

In My princess she is the real princess in Princess Hour ( Thai) she "have" to marry the prince !

Both are funny and some good romance :D
