Recommend me any good manhwas/Mangas that I can recommend to my friend. I want to introduc...

depends! what anime does your friend watch? better to start from similar genre first

She watches literally everything. She has watched more than 100+ animes of different genres I think. She watched all the popular ones like AOT, your lie on April, takopi's original sin but she doesn't like to watch animes that have 100+ episodes. She also doesn't like to read much and says that she wouldn't ever want to check out mangas or manhwas she doesn't want to read so I want recommend her a good story to change her perception about mangas/manhwas...I think she prefers animes that are a bit emotional, other than that she has watched action, mystery, psychological, shoujo (and literally every other genres)...

Oh I thik she also likes romance a lot

Wouldn’t it be easier/better to recommend mangas from anime she’s already watched?

But here are a few recs:

Fruits Basket
Beauty Pop
Full Metal Alchemist
A man and his cat (Ojisama to neko)
Natsume’s book of friends (Natsume Yuujincho)

I don't think she would like to reread things she already watched before and she already watched fruit basket and Fullmetal alchemist. The others are really good tho so I'll recommend the others to her since those are all only available in mangas. Thank you for your recommendations! I wanted to recommend something like The horizon tho (which in my opinion is one of the best things I've read. It changed the way I think and made me ponder a lot in many of the chapters. It was a masterpiece.)

Fair enough, but a lot of time the anime and manga aren’t exactly a 1-1, so even if you’ve read/watched one, there may be things missing/ different from both versions.

For example the original anime adaptations of Fruits Basket and Fullmetal Alchemist are very different from the manga.

I’ve never heard of The Horizon so I can’t say one way or another.

Hopefully you find something she’ll like.

A ghostly song (horror)
Oh dangun (action, romance its so good)
Paradise on earth (horror mystery)
White blood (action romance)
Awesome (romance, comedy)
