I just happened to scroll down and I'm going to die of dehydration because of your recommendation

http://www.mangago.zone/read-manga/5_centimeters_per_second/

Banana fish, Your Lie in April, Anohana: The flower we saw that day, I Want to Eat your Pancreas, Tokyo Ghoul, Full metal Alchemists, and 5 centimeters per second

Already saw these in anime version. Thanks anyway

Even if you watched Tokyo Ghoul, you should read it, since the manga is pretty different from the anime.
