Mangas that's made me cry are
Lover's Position
Koi to Wa Yobenai (every work by Machiya Hakoto is nice tbh)
Boku no Koe
Heart no Kakurega (the story of the second couple)
Ato Hitoiki de Ai
Soko Ni Suwaru Na
Some of Yamada Sugi's works, my fav is Aiso Tsukashi
Of course, I'm just saying the ones with suffering, but a conventional happy ending. If you want some with endings that will make you feel bitter about the end, I can say:
Calling! (The story of the first couple - Shiki and Keigo - left everyone feeling bitter about it after rading the whole manga. I personally hated it, but it is sad)
First Kiss (not quite sad, but really bittersweet)
please tell me some good manga that has the same story as "hidoku shinaide" ? It doesn't have to be the same, but some manga that made you cry
