If you liked a manga, link it. Here's some that I like
https://mangadex.org/title/1057/pandora-hearts
https://mangadex.org/title/429/shingeki-no-kyojin
https://mangadex.org/title/12033/shoujo-shuumatsu-ryokou
https://mangadex.org/title/1331/taiyou-no-ie...
I'm looking for bittersweet things like https://mangadex.org/title/22440/jumyou-wo-kaitotte-moratta-ichinen-ni-tsuki-ichimanen-de
or Your Lie in April and Plastic Memories (it doesnt need to have somebody die at the end) also if you havent read the manga I linked you should you it's a amazing story.
I haven't been able to find many good romance drama mangas so I figured I'd make a thread. I'm looking for something like the anime Golden Time (without the amnesiac protagonist) where the characters actually grow.
